Authors: Kristanto Yenny , Wijono Silviana , Tulung Casey Rebecca
Published: October 2024

There are many factors due to the increasing number of graduate students experiencing anxiety during their studies. One of the factors can be related to time management since many graduate students are students that have jobs, families, and other responsibilities. Having so much on their plate might be a cause of anxiety when it is done with poor time management on their end. Therefore, the purpose of this study is to find out whether there is a relation between time management and anxiety, and whether gender plays important role in time management among the students of Master of Education Graduate Students of XYZ University.  This research paper is a quantitative study which uses inferential statistics. The sample of this study was selected using purposive sampling technique. A total of 40 participants were recruited for this study. The data of time management were collected using a 5-point Likert scale ranging from Seldom True (1) to Very Often True (5), meanwhile for anxiety the Likert scale ranging from Not Present (1) to Very Severe (5).  The questionnaire was presented using Google Form in Bahasa then distributed through WhatsApp group. The data reliability was measured using Cronbach's Alpha with the result of 0.70. According to the survey 5 (12.5%) students had high time management, 29 (72.5%) students had moderate, and 6 (15%) students had low time management.  This study concludes that there is no correlation between time management with anxiety and the average of female students’ time management is as same as male students’ time management. In addition, regarding time management skill, it can be synthetized that most of the Master of Education Graduate Students of XYZ University are having moderate time management. Nevertheless, it is recommended that a thorough further research regarding this study should aim to investigate additional variables and factors that may contribute to the understanding of the relationship between time management and anxiety among Master of Education graduate students, so that it can have a better comprehensive evaluation in the future.

Authors: Karomah Ilo Guruilo , Dwi Astiati Siska
Published: October 2024

The aim of this research is to explore and describe students' mathematical representation abilities based on their level of mathematical ability. This type of research is descriptive with a qualitative approach. The research subjects were 25 students, 13 male students and 12 female students. Then 3 students with high, medium and low abilities were selected. The research results show that highly skilled subjects can re-present information or data from certain representations in the form of visual representations, can express mathematical equations and write down steps to solve mathematical problems in words. Subjects with moderate abilities only present information or data from certain representations in the form of visual representations and express mathematical equations. while low ability subjects can only solve problems involving mathematical expressions or equations. Basically, mathematical representation skills are very important and needed by students to understand the material provided and solve problems. If mathematical representation skills are lacking, it causes a lack of student understanding of the material provided so that students find it difficult to understand and work on the questions provided.

Authors: Carvalho Bianca Pinto , Silva Wildenilson Sinhorini Vieira da , Barros Marcelo de Almeida , Araujo Clécio Falcão , Almeida Stefânia Ordovás de
Published: October 2024

Purpose: Environmental disasters have caused various human, ecological, and economic damage worldwide. To reduce the potential damage and save lives in the short term, the volunteers are involved in support in disaster situations. Given this scenario, studies on volunteers who work in disaster contexts in Brazil proved to be an interesting and necessary research topic. Design/methodology/approach: This research employed a qualitative methodology, utilizing 16 semi-structured, in-depth interviews to gather data. The process of selecting participants was carried out through the snowball sampling technique, focusing on individuals volunteering in disaster response within the Brazilian setting. Following data collection, a thorough content analysis was undertaken. The motivations uncovered through this analysis were then meticulously compared and contrasted against the Volunteer Functions Inventory (VFI), which is rooted in the psychological functionalist theory of volunteerism. Findings: The findings of this study advance the literature by confirming four motivations for volunteers to act in disasters, as identified in the VFI: values, enhancement, protective, and social. Additionally, this study contributes by bringing to light two new motivations, knowledge, and readiness, which emerged from the content data analysis. The study also advances by clustering the behavior profiles determined from these motivations as expert, sensitive, altruistic, beginner, and social. Originality/value: Based on the results, a Disaster Volunteer Framework was proposed, which serves as a basis for developing public policies for the government and assists institutions that work in disaster management in attracting new volunteers.
Planetary boundaries as a way of assessing environmental performance: a methodological approach proposal
Authors: Leite Patricia Fernanda Dionizio , Hourneaux Junior Flavio
Published: October 2024

Objective: This study aims to demonstrate how planetary boundaries can serve as a method for evaluating the environmental performance of organizations.
Methodology: The study is based on different methods of data collection and analyses, based on the literature on planetary boundaries and their measurement, secondary data collection and the use of two illustrative examples with two companies operating in the oil and gas sector in the upstream segment.
Results: It was initially necessary to validate the downscaling of planetary boundaries to the business analysis level to apply the proposed conceptual model to two cases of companies operating in the oil and gas sector in the upstream segment. The proposed downscaling method proved to be adequate, effective, and plausible, as did the use of planetary boundaries as a method for evaluating the environmental performance of organizations.
Implications: This study established contributions of methodological and practical natures, which allows companies in the sector to evaluate and be evaluated based on the need to respect the biophysical limits of the Earth system.
Originality/Relevance: The concept of planetary boundaries provides a starting point for understanding the compatibility between the search for sustainable development and the current economic model, since the natural capital consumed is physically finite. In addition, a critical factor in this search is the role played by companies since the increased pressure on the consumption of natural resources directly impacts business operations.
विकासात्मक विकलांगताओं को समझना और उनका प्रबंधन करना
Authors:   इस्माईल नेशनल महिला पी0जी0 कॉलेज मेरठ, बेगम शाईस्ता
Published: October 2024

विकासात्मक विकलांगताओं को व्यापक श्रेणी की विकलांगताओं के रूप में वर्गीकृत किया गया है जो मुख्य चार क्षेत्रों के विकास को प्रभावित कर सकती है; जैसेः- शारीरिक, सीखना, व्यवहार तथा भाषा। विकास संबंधी विकलांगताओं के लक्षण बच्चों के विकास के सभी चरणों में दिखने की अधिक संभावना होती है, ये आमतौर पर किसी व्यक्ति की 22 वर्ष की आयु से पहले दिखाई देते हैं, हालांकि कुछ लक्षण जन्म से पहले भी बच्चों में मौजूद हो सकते हैं। विकासात्मक विकलांगताओं के कुछ उदाहरणों में ऑटिज्म, स्पाइना बिफिडा, डाउन सिंड्रोम, सेरेब्रल पाल्सी, रेट सिंड्रोम, भ्रूण अल्कोहल सिंड्रोम विकार, दृश्य हानि और गंभीर श्रवण हानि के साथ-साथ एडीएचडी जैसी न्यूरोडाइवर्जेट स्थितियां शामिल है। विकासात्मक विकलांगता वाले बच्चों को अपने जीवन के विभिन्न पहलुओं, जैसे गतिशीलता, आत्म देख-भाल, स्वतंत्र रूप से रहना, सीखना और ग्रहणशील तथा अभिव्यंजक भाषा में अतिरिक्त सहायता की आवश्यकता होती है। “विकासात्मक विकलांगता” शब्द व्यापक स्थितियों को शामिल करता है और इस शब्द का उपयोग विभिन्न संस्कृतियों और देशों में अलग-अलग तरीकों से किया जाता है। इसलिए इसका सटीक अनुमान नहीं लगाया जा सकता है कि दुनिया भर में कितने बच्चों में विकासात्मक विकलांगता है। हालांकि यह अनुमान लगाया गया है कि 5 वर्ष से कम उम्र के बच्चों में कम से कम 53 मिलियन बच्चों में विकासात्मक विकलांगता है। विभिन्न प्रकार की स्थितियों को कवर करने वाली विकास संबंधी विकलांगताओं के कारण इन कारणों को इंगित करना आसान नहीं होता है। हम आमतौर पर इन कारणों को दो श्रेणियों में बांट सकते हैं। अनुवांशिक कारण और पर्यावरणीय कारण। अनुवांशिक कारण भी विकासात्मक विकलांगता का कारण बन सकते हैं। इन कारकों के लिए अनुवांशिकी माता-पिता से विरासत में मिल सकती है या वे स्वतः स्फूर्त हो सकते हैं। अनुवांशिकी के कारण होने वाले सिंड्रोम में अक्सर विशेष विशेषताएं होती हैं जैसे डाउन सिंड्रोम जो क्रोमोसोम 21 की एक अतिरिक्त प्रतिलिपि के कारण होता है। पर्यावरणीय कारकों में पोषक तत्वों की कमी, गर्भावस्था के दौरान विषाक्त पदार्थों का सेवन, आयोडीन की कमी, संक्रमण, फोलेट की कमी आदि शामिल हो सकते हैं।
Why it’s worth avoiding as many viruses/common colds as possible: mine led to permanent disability
Authors: Eve Martin Paul
Published: October 2024

People are obsessed with the short-term effects of Covid, prioritising them over the longer-term impacts. “It was just like a minor cold, really”, they say, perhaps not realising that even mild cases of Covid have been shown to cause lasting cognitive impairment. But I also take exception with this comparison to the common cold. Because, for me, a simple cold led to lifelong disability and severe chronic health problems.

Interpretation and Application of General Anti-Avoidance Rules after BEPS and ATAD: Nordic Perspectives
Authors: Skar H. , Knuutinen R. , Koerver Schmidt P. , Croneberg R.
Published: October 2024

This article compares general measures against tax avoidance and the design of general anti-avoidance rules (GAARs) in Denmark, Finland, Norway, and Sweden. It focuses on aspects such as tax benefits, tax purposes, economic substance, and breaches of legislative purpose. The article also examines potential compliance issues between national GAARs, tax treaties, and the European Union’s Anti-Tax Avoidance Directive (ATAD). The analysis highlights variations in how the national GAARs apply economic substance considerations and the level of pragmatism allowed when assessing conflicts with the purpose of the circumvented legislation. Additionally, it shows that differences in the wording of the GAARs, such as requirements related to tax purposes, do not necessarily result in practical differences due to other GAAR elements reducing or nullifying them. For similar reasons, the authors conclude that compliance issues between the national GAARs and the ATAD GAAR’s requirements are unlikely, despite some differences in wording. Whilst focusing on the Nordic region, the article offers insights relevant to broader international contexts, as the diverse approaches, distinctions, and issues identified mirror tax developments worldwide.

Published: October 2024

La presente investigación buscó dar cuenta de la posible existencia de asociaciones significativas entre las variables Actitud ante la Sexualidad y Representaciones hacia la Expresión de Género. Además, se indagó sobre las posibles diferencias entre la adolescen- cia y la adultez respecto a esto. Se trató de un diseño no experimental, con enfoque cuanti- tativo, de alcance descriptivo-correlacional y de corte transversal. En cuanto a la muestra, estuvo compuesta por 246 sujetos mayores de 15 años, representando la adolescencia en un rango etario de entre 14 a 21 años o más (43.37%) y considerando la adultez desde los 25 años hasta los 64 (53,62%), a partir de un muestreo intencional y por conveniencia. Se aplicó la Escala de Actitud hacia la Sexualidad (ATSS) (Diéguez Ruibal et al., 2005); un Cuestionario de Ideario Masculino/Femenino (Soto Guzmán, 2017); y un cuestionario sociodemográfico elaborado ad-hoc a los fines de la investigación. Los resultados eviden- ciaron que existen diferencias significativas en relación a la edad de los participantes, siendo que los adolescentes percibieron menor ideario de género junto con una actitud más liberal hacia las actitudes referidas a la sexualidad en comparación con los adultos. Por otro lado, las personas masculinas mostraron actitudes más liberales que las mujeres en algunas dimensiones de dicha variable. A su vez, se evidenció cómo las personas no creyentes poseen actitudes más liberales que las creyentes en algunas dimensiones, y en relación a esto, se halló una asociación significativa entre las prácticas religiosas con tales actitudes. Por último, se concluye que se debe considerar un muestreo más representativo, como también diseños longitudinales para comprender mejor la relación entre dichas variables, así como instrumentos de medición validados en Argentina.

Published: October 2024

This study examined the impact of Development Bank Credit Financing (DBCF) on the performance of small and medium enterprises, employment generation growth, financial asset growth and profit growth in Nigeria. A survey research design was employed; 398 SMEs were randomly selected from the beneficiaries of DBCF loans. Descriptive analysis was conducted, and binary logistic regression was employed to examine the impact of DBFC on SMEs. The result showed that the DBCF Amount of Credit Loan Received (ACLR) positively impacted the growth of SMEs, given their beta coefficients of 0.510 and 0.765, respectively. Their respective p-values and Wald statistics of 0.001, 0.001 and 14.050, 13.486 show their significance level. However, it was discovered that there is no significant impact of DBCF on the profit growth of SMEs in Nigeria. The average monthly tax payment (AVMTL) made by the micro, small and medium enterprises (MSMEs) was established to negatively impact on SMEs profit. The coefficient (β) = - 1.004 (100.4%) showed that a unit change in the AVMTL while holding other variables constant led to about 1.004 unit decline in the logit, SMEs profit. Specifically, it means MSMEs profit will decrease by the exact amount of what is paid as tax.

Authors: Merino Guanga Manuel Patricio
Published: October 2024

EL artículo analiza las diferencias y similitudes en los sistemas educativos de Argentina y Ecuador, abordando la persistente desigualdad educativa en ambos países. El problema central radica en las disparidades en la calidad educativa entre regiones urbanas y rurales, y entre distintos grupos socioeconómicos. El objetivo principal del estudio es identificar los factores estructurales, políticos y sociales que contribuyen a esta desigualdad y evaluar la efectividad de las políticas educativas implementadas en ambos países para mitigarla. La metodología empleada es un enfoque comparativo cualitativo basado en el análisis de documentos legislativos, informes gubernamentales, estudios académicos y datos estadísticos. Las conclusiones destacan que, a pesar de los esfuerzos por democratizar el acceso a la educación, las desigualdades persisten debido a la fragmentación administrativa y la desigualdad en la distribución de recursos. Se proponen reformas estructurales que promuevan una mayor equidad y calidad educativa, incluyendo una mejor coordinación entre las políticas nacionales y regionales, y un enfoque más inclusivo en la gobernanza educativa.
THE ESSENCE OF ENGLISH FOR SPECIFIC PURPOSES (ESP) AND THE ROLE OF NEW TECHNOLOGIES IN ESP TEACHING
Authors: Kostanyan Ulyana
Published: October 2024

English for Specific Purposes (ESP) programs are specifically designed for learners who desire to enhance their English proficiency in a specific professional field of study, which is typically taught at universities. These programs are designed to provide students with the English they need for specific academic subjects, such as Economics, Psychology, Management, etc.

The 21st century brought a new flow of challenges. A growing number of cross-national projects, the need to raise intercultural awareness, the overwhelming number of inter-state activities, and the desire to become a global citizen are some of the consequences. The full development of skills that guarantee high-level communication between future specialists and their foreign colleagues in various academic and professional settings is a crucial factor in the efficiency and achievement of specialists’ work. All the above-mentioned factors had a significant impact on educational policies and classroom activities. Educators started looking for new techniques for teaching English. New technologies in the ESP classroom encourage students to be active and work together, create an authentic, supportive, and productive learning environment that helps to improve learning achievements, make the learning process more successful, and allow students to acquire relevant knowledge.
Las condiciones institucionales para fundamentar una política municipal antidiscriminatoria hacia los inmigrantes indígenas de Tuxtla Gutiérrez, Chiapas, México
Authors: Zúñiga Flores Rigoberto , Jauregui Díaz José Alfredo , Ávila Sánchez María de Jesús
Published: October 2024

Esta investigación tiene el objetivo de realizar un análisis interpretativo de las instituciones formales del Ayuntamiento municipal de Tuxtla Gutiérrez, para valorar si existen los fundamentos legales y políticos que permitan implementar una política antidiscriminatoria hacia los inmigrantes indígenas que habitan en la ciudad. Para lograr los propósitos del estudio se desarrolló un enfoque cualitativo y se utilizó un método de análisis de contenido para interpretar los documentos normativos; posteriormente basado en categorías del Nuevo Institucionalismo Histórico (NIH) se realizó un análisis de los acontecimientos externos que han influido en los cambios institucionales. Entre los resultados se detectó que el municipio no crea instituciones, pero puede proponerlas al Congreso, sin embargo, se encontró un periodo legislativo donde se crean leyes que vinculan al municipio en temas de Derechos Humanos y la no discriminación. Dichos cambios institucionales surgen a partir de la firma de un convenio de trabajo entre Gobierno del Estado (2006-2012) y la ONU, el cual llevó a constitucionalizar un plan de desarrollo centrado en el ser humano, pero para el siguiente sexenio (2012-2018) promovieron contrarreformas que sacaron del centro de atención al desarrollo humano, no obstante, la ley antidiscriminatoria sigue vigente pero el desinterés en el tema no permite que el Ayuntamiento de Tuxtla instrumente una política contra la discriminación.
Expresiones liberadoras y transformadoras de un mundo socialmente prefigurado: arte femenino trasgresor
Authors: Beltrán Castellanos Ara , Beltrán Castellanos Mirla
Published: October 2024

El arte, es una forma de representar y manifestar sentimientos y emociones humanas de armonía, amor y serenidad; y a la vez es una forma de presentar y exteriorizar, hacer visibles las injusticias, malas prácticas culturales y adoctrinamientos.                                               
En el presente artículo, se presentarán una serie de reflexiones a partir de las experiencias artísticas de dos mujeres talentosas colombianas, que encontraron en las representaciones visuales una forma de denunciar el control femenino impartido por la educación conductual, las instituciones como la Iglesia y la publicidad. Así mismo, se analizó la continua represión femenina que aún se presenta en nuestros días, las causas de la violencia de género y por qué el machismo sigue enraizado en la cotidianidad de la sociedad. Estas reflexiones se sitúan en la revisión de la discusión que plantea la autora de la tesis, en la que se vinculan elementos de la educación tradicional colombiana y la expresión artística femenina contemporánea, desde casos particulares de dos artistas que buscan romper con la tradición, las maneras, las formas y los roles que se le han querido adjudicar a lo femenino por parte de una mirada de una sociedad igualmente tradicional y por qué no, anclada en una atemporalidad restrictiva.                                                                                                                
Al hacer el análisis de la expresión artística femenina en Colombia, se evidencia que es posible una emancipación de la mujer y comprobar que, a pesar de la represión continua, se pueden fijar propuestas como las aquellas que provienen de las manifestaciones artísticas que hoy se analizarán para llegar a la liberación.

Published: October 2024

As the largest archipelagic country in the world and located right in between of two oceans, Indonesia benefited from its geographical location especially since the Malacca Strait become the major marine traffic in the world. Not only that, Indonesia also established three major waterways called Archipelagic Sea Lanes (ASL) where every international ship obliged to passing by Indonesian territorial waters without disturbance with the straits such as Sunda Strait and Lombok Strait as the major strait. In economic development, these policies impacted the growth of several major cities in Indonesia such as Medan in the Sumatera Island, Jakarta and Surabaya in Java Island and Makassar in Sulawesi Island. The archipelagic countries as defined in the UNCLOS as the waters around, between and connecting the islands belong to the Indonesian irrespective the size or dimension, therefore a constant vigilant must be conduct by Indonesian Government. In this research, we utilize AIS data from third party then analyze from the numbers of ships travelling in the waterway and the needs to maintain a state-of-the-art monitoring of every ship in the territorial waters.
 
ABSTRAK
Sebagai negara kepulauan yang terbesar didunia dan terletak diantara dua samudera, Indonesia diuntungkan dari letak geografisnya terlebih sejak Selat Malaka menjadi jalur pelayaran utama dunia. Tidak hanya itu, Indonesia juga membuka tiga jalur utama pelayaran yang disebut dengan Alur Laut Kepulauan Indonesia (ALKI) dimana setiap kapal internasional dapat melewati alur pelayaran tersebut dengan damai dan tidak mengganggu kedaulatan Indonesia contohnya adalah Selat Sunda dan Selat Lombok. Dari perkembangan ekonomi, kebijakan tersebut berdampak pada pembangunan kota-kota besar seperti Medan di Pulau Sumatera, Jakarta dan Surabaya di Pulau Jawa dan Makassar di Pulau Sulawesi. Definisi negara kepulauan sesuai UNCLOS adalah segala perairan disekitar, diantara dan yang menghubungkan antara pulau-pulau merupakan bagian dari wilayah Indonesia apapun ukuran dan dimensinya, oleh sebab itu pengawasan yang berkesinambungan harus terus dilakukan oleh Pemerintah Indonesia. Penelitian ini menggunakan data AIS (Automatic Identification System) untuk melihat lalu lintas pelayaran di Indonesia serta mengambil langkah-langkah strategis untuk mengawasi pergerakan dari kapal-kapal yang berada di wilayah perairan teritorial tersebut.
Revisiting the Slot-to-Coefficient Transformation for BGV and BFV
Authors: Geelen Robin
Published: October 2024

Numerous applications in homomorphic encryption require an operation that moves the slots of a ciphertext to the coefficients of a different ciphertext. For the BGV and BFV schemes, the only efficient algorithms to implement this slot-to-coefficient transformation were proposed in the setting of non-power-of-two cyclotomic rings. In this paper, we devise an FFT-like method to decompose the slot-to-coefficient transformation (and its inverse) for power-of-two cyclotomic rings. The proposed method can handle both fully and sparsely packed slots. Our algorithm brings down the computational complexity of the slot-to-coefficient transformation from a linear to a logarithmic number of FHE operations, which is shown via a detailed complexity analysis.

The new procedures are implemented in Microsoft SEAL for BFV. The experiments report a speedup of up to 44 times when packing 2^12 elements from GF(8191^8). We also study a fully packed bootstrapping operation that refreshes 2^15 elements from GF(65537) and obtain an amortized speedup of 12 times.
Amortizing Circuit-PSI in the Multiple Sender/Receiver Setting
Authors: van Baarsen Aron , Stevens Marc
Published: October 2024

Private set intersection (PSI) is a cryptographic functionality for two parties to learn the intersection of their input sets, without leaking any other information. Circuit-PSI is a stronger PSI functionality where the parties learn only a secret-shared form of the desired intersection, thus without revealing the intersection directly. These secret shares can subsequently serve as input to a secure multiparty computation of any function on this intersection.

In this paper we consider several settings in which parties take part in multiple Circuit-PSI executions with the same input set, and aim to amortize communications and computations. To that end, we build up a new framework for Circuit-PSI around generalizations of oblivious (programmable) PRFs that are extended with offline setup phases. We present several efficient instantiations of this framework with new security proofs for this setting. As a side result, we obtain a slight improvement in communication and computation complexity over the state-of-the-art semi-honest Circuit-PSI protocol by Bienstock et al. (USENIX '23). Additionally, we present a novel Circuit-PSI protocol from a PRF with secret-shared outputs, which has linear communication and computation complexity in the parties' input set sizes, and is able to realize a stronger security notion. Lastly, we derive the potential amortizations over multiple protocol executions, and observe that each of the presented instantiations is favorable in at least one of the multiple-execution settings.
The Perils of Limited Key Reuse: Adaptive and Parallel Mismatch Attacks with Post-processing Against Kyber
Authors: Guo Qian , Mårtensson Erik , Åström Adrian
Published: October 2024

The Module Learning With Errors (MLWE)-based Key Encapsulation Mechanism (KEM) Kyber is NIST's new standard scheme for post-quantum encryption. As a building block, Kyber uses a Chosen Plaintext Attack (CPA)-secure Public Key Encryption (PKE) scheme, referred to as Kyber.CPAPKE. In this paper we study the robustness of Kyber.CPAPKE against key mismatch attacks.

We demonstrate that Kyber's security levels can be compromised if having access to a few mismatch queries of Kyber.CPAPKE, by striking a balance between the parallelization level and the cost of lattice reduction for post-processing. This highlights the imperative need to strictly prohibit key reuse in Kyber.CPAPKE.

We further propose an adaptive method to enhance parallel mismatch attacks, initially proposed by Shao et al. at AsiaCCS 2024, thereby significantly reducing query complexity. This method combines the adaptive attack with post-processing via lattice reduction to retrieve the final secret key entries. Our method proves its efficacy by reducing query complexity by 14.6 % for Kyber512 and 7.5 % for Kyber768/Kyber1024.

Furthermore, this approach has the potential to improve multi-value Plaintext-Checking (PC) oracle-based side-channel attacks and fault-injection attacks against Kyber itself.
Truncated multiplication and batch software SIMD AVX512 implementation for faster Montgomery multiplications and modular exponentiation
Authors: Didier Laurent-Stéphane , Mrabet Nadia , Glandus Léa , Robert Jean-Marc
Published: October 2024

This paper presents software implementations of batch computations, dealing with multi-precision integer operations. In this work, we use the Single Instruction Multiple Data (SIMD) AVX512 instruction set of the x86-64 processors, in particular the vectorized fused multiplier-adder VPMADD52. We focus on batch multiplications, squarings, modular multiplications, modular squarings and constant time modular exponentiations of 8 values using a word-slicing storage. We explore the use of Schoolbook and Karatsuba approaches with operands up to 4108 and 4154 bits respectively. We also introduce a truncated multiplication that speeds up the computation of the Montgomery modular reduction in the context of software implementation. Our Truncated Montgomery modular multiplication improvement offers speed gains of almost 20 % over the conventional non-truncated versions. Compared to the state-of-the-art GMP and OpenSSL libraries, our speedup modular operations are more than 4 times faster. Compared to OpenSSL BN_mod_exp_mont_consttimex2 using AVX512 and madd52* (madd52hi or madd52lo) in 256-bit registers, in fixed-window exponentiations of sizes

Optimizing $c$-sum BKW and Faster Quantum Variant for LWE
Authors: Cao Jinzheng , Cheng Qingfeng , Weng Jian
Published: October 2024

The Learning with Errors (LWE) problem has become one of the most prominent candidates of post-quantum cryptography, offering promising potential to meet the challenge of quantum computing. From a theoretical perspective, optimizing algorithms to solve LWE is a vital task for the analysis of this cryptographic primitive. In this paper, we propose a fine-grained time/memory trade-off method to analyze c-sum BKW variants for LWE in both classical and quantum models, then offer new complexity bounds for multiple BKW variants determined by modulus q, dimension k, error rate alpha, and stripe size b. Through our analysis, optimal parameters can be efficiently found for different settings, and the minimized complexities are lower than existing results. Furthermore, we enhance the performance of c-sum BKW in the quantum computing model by adopting the quantum Meet-in-the-Middle technique as c-sum solver instead of the naive c-sum technique. Our complexity trade-off formula also applies to the quantum version of BKW, and optimizes the theoretical quantum time and memory costs, which are exponentially lower than existing quantum c-sum BKW variants.
A Note on Related-Tweakey Impossible Differential Attacks
Authors: Bonnetain Xavier , Lallemand Virginie
Published: October 2024

In this note we review the technique proposed at ToSC 2018 by Sadeghi et al. for attacks built upon several related-tweakey impossible differential trails. We show that the initial encryption queries are improper and lead the authors to misevaluate a filtering value in the key recovery phase. We identified 4 other papers (from Eurocrypt, DCC, and 2 from ToSC) that follow on the results of Sadeghi et al. and in three of them the flawed technique was reused.

We thus present a careful analysis of these types of attacks and give generic complexity formulas similar to the ones proposed by Boura et al. at Asiacrypt 2014. We apply these to the aforementioned papers and provide patched versions of their attacks. The main consequence is an increase in the memory complexity. We show that in many cases (a notable exception being quantum impossible differentials) it is possible to recover the numeric time estimates of the flawed analysis, and in all cases we were able to build a correct attack reaching the same number of rounds.
Computing Orientations from the Endomorphism Ring of Supersingular Curves and Applications
Authors: Eriksen Jonathan , Leroux Antonin
Published: October 2024

This work introduces several algorithms related to the computation of orientations in endomorphism rings of supersingular elliptic curves. This problem is at the heart of several results regarding the security of oriented-curves in isogeny-based cryptography. Under the Deuring correspondence, it can be expressed purely in terms of quaternion and boils down to representing integers by ternary quadratic forms. Our main contribution is to show that there exist efficient algorithms to solve this problem for quadratic orders of discriminant

up to

O
(

. Our approach improves upon previous results by increasing this bound from

to

and removing some heuristics. We introduce several variants of our new algorithm and provide a careful analysis of their asymptotic running time (without heuristic when it is possible). The best proven asymptotic complexity of one of our variants is

in average. The best heuristic variant has a complexity of

. We then introduce several results regarding the computation of ideals between oriented orders. The first application of this is a simplification of the known reduction from vectorization to computing the endomorphism ring, removing the assumption on the factorization of the discriminant. As a second application, we relate the problem of computing fixed-degree isogenies between supersingular curves to the problem of computing orientations in endomorphism rings, and we show that for a large range of degree

d

, our new algorithms improve on the state-of-the-art, and in important special cases, the range of degree

for which there exist a polynomial-time algorithm is increased. In the most special case we consider, when both curves are oriented by a small degree endomorphism, we show heuristically that our techniques allow the computation of isogenies of any degree, assuming they exist.
Constant-Round YOSO MPC Without Setup
Authors: Kolby Sebastian , Ravi Divya , Yakoubov Sophia
Published: October 2024

YOSO MPC (Gentry et al., Crypto 2021) is a new MPC framework where each participant can speak at most once. This models an adaptive adversary’s ability to watch the network and corrupt or destroy parties it deems significant based on their communication. By using private channels to anonymous receivers (e.g. by encrypting to a public key whose owner is unknown), the communication complexity of YOSO MPC can scale sublinearly with the total number N of available parties, even when the adversary’s corruption threshold is linear in N (e.g. just under N/2). It was previously an open problem whether YOSO MPC can achieve guaranteed output delivery in a constant number of rounds without relying on trusted setup. In this work, we show that this can indeed be accomplished. We demonstrate three different approaches: the first two (which we call YaOSO and YOSO-GLS) use two and three rounds of communication, respectively. Our third approach (which we call YOSO-LHSS) uses O(d) rounds, where d is the multiplicative depth of the circuit being evaluated; however, it can be used to bootstrap any constant-round YOSO protocol that requires setup, by generating that setup within YOSO-LHSS. Though YOSO-LHSS requires more rounds than our first two approaches, it may be more practical, since the zero knowledge proofs it employs are more efficient to instantiate. As a contribution of independent interest, we introduce a verifiable state propagation UC functionality, which allows parties to send private message which are verifiably derived in the “correct” way (according to the protocol in question) to anonymous receivers. This is a natural functionality to build YOSO protocols on top of.
Quantum Procedures for Nested Search Problems
Authors: Schrottenloher André , Stevens Marc
Published: October 2024

In this paper we study search problems that arise very often in cryptanalysis: nested search problems, where each search layer has known degrees of freedom and/or constraints. A generic quantum solution for such problems consists of nesting Grover's quantum search algorithm or amplitude amplification (QAA) by Brassard et al., obtaining up to a square-root speedup on classical algorithms. However, the analysis of nested Grover or QAA is complex and introduces technicalities that in previous works are handled in a case-by-case manner. Moreover, straightforward nesting of l layers multiplies the complexity by a constant factor (pi/2)^l.

In this paper, we aim to remedy both these issues and introduce a generic framework and tools to transform a classical nested search into a quantum procedure. It improves the state-of-the-art in three ways: 1) our framework results in quantum procedures that are significantly simpler to describe and analyze; 2) it reduces the overhead factor from (pi/2)^l to sqrt(l); 3) it is simpler to apply and optimize, without needing manual quantum analysis. We give generic complexity formulas and show that for concrete instances, numerical optimizations enable further improvements, reducing even more the gap to an exact quadratic speedup.

We demonstrate our framework by giving a tighter analysis of quantum attacks on reduced-round AES.
Discrete Logarithm Factory
Authors: Al Aswad Haetham , Thomé Emmanuel , Pierrot Cécile
Published: October 2024

The Number Field Sieve and its variants are the best algorithms to solve the discrete logarithm problem in finite fields (except for the weak small characteristic case). The Factory variant accelerates the computation when several prime fields are targeted. This article adapts the Factory variant to non-prime finite fields of medium and large characteristic. A precomputation, solely dependent on an approximate finite field size and an extension degree, allows to efficiently compute discrete logarithms in a constant proportion of the finite fields of the given approximate size and extension degree. We combine this idea with two other variants of NFS, namely the tower and special variant. This combination improves the asymptotic complexity. We also notice that combining our approach with the MNFS variant would be an unnecessary complication as all the potential gain of MNFS is subsumed by our Factory variant anyway. Furthermore, we demonstrate how Chebotarev's density theorem allows to compute the density of finite fields that can be solved with a given precomputation. Finally, we provide experimental data in order to assess the practical reach of our approach.
