Atom typing in the CDK
Authors: Willighagen Egon
Published: January 2025

Atom typing is one of principal activities in chemoinformatics. Atom types provide additional information that cannot be derived from the connection table that is being used, or may define what force fields terms should be used. This makes perception of atom types very important. The CDK has a few places where atom types are perceived. The HydrogenAdder and ValencyChecker are two examples.
Programming in the Life Sciences #10: JavaScript Object Notation (JSON)
Authors: Willighagen Egon
Published: January 2025

As said, JSON is the format we will use as serialization format for answers given by the Open PHACTS LDA. The API actually supports XML, RDF, HTML, and TSV too, but I think JSON is a good balance between expressiveness and compactness.
Centralized or decentralized?
Authors: Willighagen Egon
Published: January 2025

Peter wondered if data should be stored centralized or decentralized, when Deepak blogged about Freebase and Metaweb. Now, I haven’t really looked into these two projects, but the question of centralized versus decentralized is interesting. It’s MySQL versus the world wide web; it’s the PubChem compound ID versus the InChI;

Published: January 2025

Data science literacy is an important skill in the digital era, but high school students' understanding of this concept is still limited. This study aims to improve students' data science literacy through interactively designed training, including theory delivery and discussion sessions. This study was conducted in Surabaya involving 32 students from five partner schools. The research instruments included a pre-training questionnaire to measure the level of initial understanding, training materials in the form of presentations and educational case studies, and a post-training questionnaire to evaluate the results. The analysis was carried out quantitatively based on the results of the pre-test and post-test, and qualitatively through observation and discussion. The results showed a significant increase in student understanding, with the average post-test score increasing from 45% to 80%. Positive responses from students and teachers indicated that the case study-based training approach was relevant and effective. However, obstacles such as differences in student understanding levels and limited training duration were obstacles to implementation in maximizing knowledge for participants.
Für ein diskriminierungsfreies neues Abtreibungsrecht
Authors: Degener Theresia , Bliecke Vanessa
Published: January 2025

Die Diskussion um ein neues Abtreibungsrecht hat durch einen fraktionsübergreifenden Gesetzentwurf neue Dynamik gewonnen. Eine kontroverse Frage beantwortet der Entwurf allerdings nicht final: Ist es zulässig, einen gesonderten Erlaubnistatbestand für sogenannte embryopathische Abtreibungen aufzunehmen, also die Abtreibungsmöglichkeiten zu erweitern, wenn bei dem Fötus/Embryo eine potenzielle Behinderung festgestellt wird? Dieser Beitrag argumentiert, dass jedenfalls die Aufnahme einer eigenständigen embryopathischen Indikation mit völker- und verfassungsrechtlichen Wertungen unvereinbar ist.
The impact of political ideologies on renewable energy adoption
Authors: Ghorpade Anushka , Paralikar Kunal
Published: January 2025

Due to the growing urgency of climate change, renewable energy technologies have become an increasingly popular source of energy. However, differing perceptions on the urgency of climate change along political party lines may result in variable rates of adoption of these renewable energy technologies. This study explores the hypothesis that Republican states are less inclined to adopt renewable energy technologies than Democratic states. To test this hypothesis, we analyzed overall renewable energy production across two Democratic states (Washington and California) and two Republican states (Texas and Florida). We investigated correlations between the energy production of each state and used t-tests to assess statistical significance. Contrary to our hypothesis, however, we concluded that there was no observable correlation between political ideologies and renewable energy adoption. In fact, Texas, a Republican state, showed the fastest renewable energy production growth rate and produced the most wind energy compared to California, Washington, and Florida. Our findings suggested that factors beyond party lines likely influence state-level decisions regarding renewable energy sources. Understanding these factors is critical to create policies to combat climate change and drive renewable energy adoption worldwide.

A lozenge is a form of solid pharmaceutical preparation designed to dissolve slowly in the oral cavity, providing both local and systemic effects. In lozenge formulation, binders play an important role in ensuring tablet hardness and appropriate dissolution time. This study aims to compare the effects of synthetic and natural binders on the physical properties and performance of lozenges. Synthetic binders such as PVP, CMC Na, and Hydroxypropyl Methylcellulose (HPMC) tend to provide higher tablet hardness and more controlled dissolution times. Meanwhile, natural binders such as maltodextrin, gum arabic, and jackfruit seed starch show good abilities to enhance tablet cohesion, with the additional benefits of biocompatibility and biodegradability. The research results indicate that synthetic binders provide better physical stability, while natural binders are preferred due to their environmentally friendly properties and ability to improve patient acceptance.

À Addipsy, centre ambulatoire d’addictologie et de psychiatrie générale à Lyon, l’évaluation pluridisciplinaire en addictologie permet de soutenir la personne en soin dans ses orientations thérapeutiques. L’évaluation en ergothérapie, qui s’inspire du Modèle de l’occupation humaine, utilise notamment l’OCAIRS, une grille d’entretien semi-structurée qui permet de définir la participation occupationnelle de la personne rencontrée. Cet outil a un intérêt tout particulier en ergothérapie dans le cadre des rencontres avec les personnes souffrant d’addiction. En effet, les déséquilibres occupationnels sont un facteur de risque majeur dans les prises de produit. Parmi ces déséquilibres occupationnels, on trouve l’imprévu.
Dans cet article, il s’agit de présenter ce protocole d’évaluation autour d’une vignette clinique ; puis d’exposer les objectifs et le déroulement du groupe « Imprévu » qui permet de travailler sur les capacités d’adaptation. En effet, après l’évaluation pluridisciplinaire, les personnes peuvent participer à ce groupe animé par l’ergothérapeute, afin d’être soutenues dans leurs capacités à gérer les imprévus qui souvent les déstabilisent et déclenchent des comportements addictifs au quotidien.

This study investigated the influence of strategic management practices on the survival rates of small and medium-sized enterprise (SME) start-ups in Taita Taveta County, Kenya. The study focused on five key strategic management practices: strategic planning quality, leadership effectiveness, strategic innovation, strategic market orientation, and access to financing. Specifically, it examined how these practices impacted SME survival indicators such as business longevity, financial stability, and market presence. A descriptive research design was adopted, and data were collected using structured questionnaires distributed to SME owners and managers within the county. The sample included both established and relatively new SMEs operating across various sectors. The findings revealed that strategic planning quality, characterized by goal setting, resource allocation, and risk assessment, significantly influenced SME sustainability. Leadership effectiveness, particularly in decision-making and adaptability, was found to enhance organizational resilience. Strategic innovation through product and process improvements, as well as technology adoption, also contributed positively to SME growth. Strategic market orientation, emphasizing customer focus, market responsiveness, and competitor analysis, improved market positioning and survival. Furthermore, access to financing, including credit availability and cost of funding, emerged as a critical determinant of SME longevity. The study concluded that the adoption of comprehensive strategic management practices significantly enhanced the survival and competitiveness of SME start-ups. The findings underscored the need for SME stakeholders to prioritize strategic approaches in operations to address challenges and ensure long-term success. Recommendations were provided to policy-makers and practitioners to support SME development through targeted interventions.
Una propuesta de análisis semiótico-discursivo de los efectos argumentativos del discurso
Authors: Colman Alex Darío
Published: January 2025

El artículo presenta una propuesta para analizar los efectos argumentativos del discurso. Esta combina herramientas de la semiótica de Greimas con otras de los estudios lingüísticos, semióticos, semio-discursivos, del discurso y argumentativos. La propuesta se centra en los procesos de configuración del sentido que permiten reconocer un discurso como “argumentativo”. Dicha configuración anida en la escenificación de una situación argumentativa y su programación narrativa, lo que permite identificar tres recorridos: “sostener una tesis”, “contraargumentar” y “persuadir”. Esta caracterización del discurso argumentativo se sostiene en un enfoque teórico-epistemológico que conecta las nociones de “forma” e “información” de Simondon con el problema de la recepción discursiva y sus efectos. La primera sección del artículo reseña sintéticamente contribuciones relevantes sobre la relación entre semiótica y argumentación. La segunda detalla el diseño teórico-epistemológico y metodológico de la propuesta. Finalmente, la tercera sección ilustra este enfoque mediante el análisis de un artículo de investigación de historia reciente argentina. Los resultados del análisis tienden a mostrar las potencialidades de esta propuesta para comprender, en un marco semiótico-narrativo, los procesos de configuración del sentido que sostienen la producción de efectos argumentativos.
Evaluación de la calidad de los cuidados de enfermería en unidades de cuidados intensivos neonatales desde la perspectiva de los padres o cuidadores
Authors: Paredes Núñez Cynthia Lissette
Published: January 2025

La calidad de los cuidados de enfermería en las Unidades de Cuidados Intensivos Neonatales (UCIN) es esencial para garantizar el bienestar de los neonatos y sus cuidadores. Este estudio tuvo como objetivo diseñar, validar y aplicar un instrumento para evaluar la percepción de los cuidadores sobre la calidad del cuidado en UCIN. Se desarrolló la Escala de Satisfacción Parental en UCIN (ESPU), que incluyó 16 preguntas distribuidas en cuatro dimensiones: Información y Comunicación, Empatía y Apoyo Emocional, Participación en el Cuidado, y Organización y Ambiente. El instrumento demostró ser confiable, con un alfa de Cronbach global de 0,89. Se aplicó a 36 cuidadores mediante un muestreo no probabilístico, obteniendo resultados positivos en general. Las dimensiones mejor valoradas fueron Organización y Ambiente (85,00% de respuestas positivas) y Empatía y Apoyo Emocional (73,00%), reflejando el esfuerzo del personal de enfermería por crear un entorno seguro y brindar un trato empático. Sin embargo, Información y Comunicación mostró una mayor variabilidad en las respuestas (13,00% en desacuerdo), indicando áreas de mejora en la personalización de la información. La Participación en el Cuidado presentó la valoración más baja (42,00% positivas), sugiriendo la necesidad de incluir más activamente a los cuidadores en el proceso de atención. Este estudio resalta la importancia de un enfoque integral y humanizado en las UCIN, basado en la comunicación efectiva, el apoyo emocional y la inclusión parental, para optimizar tanto la experiencia de los cuidadores como los resultados en salud.
Matrix Theory Approach to Fuzzy Hypersoft Set in Multi-Criteria Airline Selection
Authors: Jafar Muhammad Naveed , Saqlain Muhammad
Published: January 2025

When we talk about decision-making then it means we have to tackle the attributes and alternatives, and it becomes difficult when attributes are further subdivided. The hypersoft theory allows us to handle further bifurcated attributes. This paper is aim to provide the legal way to deal with multi-criteria decision-making (MCDM) problems in the sense of further subdividing attributes by applying the concept of fuzzy hypersoft matrices (FHSM’s). Since matrices provide us with a fast and reliable way to solve problems. In this paper, we have proposed the concept of FHSM with their operators, theorems, propositions, and decision-making (DM) algorithms. The proposed algorithms have been supported with real-life application of airline selection while you have to take any flight. The concept of further bifurcation gives more accurate and refined results than the existing techniques, along with the implication of FHSM. In the future, the proposed concept can be implemented in other hybrids of hypersoft set theory with DM algorithms. The challenges faced in implication can be dealt with machine learning algorithms for fast and more accurate results.

Bibliotherapy is a technique used in group guidance services as an alternative to overcoming individual developmental problems in social life. This technique involves three stages, namely identification, catharsis, and insight. By reading books, learners can gain cognitive, affective, and psychomotor benefits. Group guidance services with bibliotherapy methods can also increase learners' engagement and make them more active in the learning process. This research explores the effectiveness of bibliotherapy in the context of group guidance. Using selected books, learners are allowed to reflect, identify feelings, and gain new insights. The results show that bibliotherapy can increase self-understanding, reduce stress, and strengthen social skills. Therefore, group guidance services using this approach can be a valuable alternative in helping learners overcome life's challenges.

Authors: Syarif Maulidin  , M. Isla Maulana  , Ulin Nuha
Published: January 2025

This study aims to analyze the role of Syajarotun al-Ma’arif in character education through its teachings on aqidah and fiqh. The research method used is a literature study with a qualitative approach, analyzing the texts contained in the book to explore its contribution to the formation of an individual’s character. The research findings show that the aqidah teachings in Syajarotun al-Ma’arif focus on strengthening faith in Allah, angels, His scriptures, and the Day of Judgment, accompanied by the cultivation of attitudes such as trust in God, patience, and humility. Meanwhile, the fiqh education in this book emphasizes ritual obligations paired with the development of good character traits, such as honesty, social concern, and proper manners in interacting with others. These two teachings complement each other in shaping a character based on high moral values in Islam. This study concludes that Syajarotun al-Ma’arif plays a significant role in character education, both spiritually and socially, providing a strong foundation for shaping responsible and moral individuals.

VIOLÊNCIA CONTRA MULHER E REDE DE APOIO: REVISÃO INTEGRATIVA
Authors: Nascimento Clarice Allayne Epaminondas Lopes do , Dourado Jakson Luis Galdino
Published: January 2025

A violência doméstica é um padrão de comportamento abusivo que ocorre entre pessoas que têm ou tiveram um relacionamento íntimo. Pode afetar qualquer pessoa, independentemente de sua idade, gênero, orientação sexual, raça, etnia ou status socioeconômico. Com o objetivo de compreender essa realidade, o presente trabalho busca realizar uma revisão integrativa da literatura, com o intuito de conhecer as estratégias de enfrentamento de mulheres vítimas de violência e as redes de apoio que as ajudam a lidar com essas ocorrências. Utilizando as bases de dados do Scielo, PEPSIC e BV-PSI, foram revisados 11 artigos publicados entre os anos de 2018 e 2023, os quais avaliavam a violência contra a mulher e suas redes de apoio. Os artigos apontaram a ineficácia da rede de apoio, evidenciando também que a maioria das mulheres que sofrem violência não denuncia seus agressores e, muitas vezes, se culpam pela situação que estão vivenciando. Por fim, o trabalho indica uma prevalência das violências física, psicológica e moral, tipificações mais comuns nos lares e que causam danos emocionais graves na vida das mulheres.
A EXPERIÊNCIA, O CONHECIMENTO E A VERDADE NO TRATADO DA EMENDA DO INTELECTO DE BENEDICTUS DE SPINOZA: DIFERENÇAS COM RENÉ DESCARTES
Authors: Turbae Junior Armando
Published: January 2025

A ideia presente nas Meditações de René Descartes, de que o puro pensamento não contém em si nenhum vestígio com origem nos sentidos, pode parecer concordar integralmente com o Tratado da Emenda do Intelecto de Benedictus de Spinoza, pelo fato de nesta obra de juventude o filósofo holandês priorizar o tratamento das ideias e não a realidade corporal. Analisaremos quais diferenças existentes no método empregado por Descartes, na busca de um fundamento seguro para o conhecimento, e o método em Spinoza de busca do “bem verdadeiro”, como também procuraremos esclarecer os significados, nas duas obras, das ideias de experiência, conhecimento e verdade. Verificaremos o lugar ocupado pela experiência, os afetos e a razão no Tratado da Emenda do Intelecto. Após termos problematizado essas questões, veremos se é possível afirmar haver no TIE o esboço de um programa de natureza política.
Lights, camera, revolution! Using pedagogical videos to teach about worker-owned co‑operatives in business schools
Authors: Michaud Myriam , Audebrand Luc K
Published: January 2025

Despite its advantages in terms of sustainable development, the co-operative business model is still little known and largely underestimated by the general population. Even in business schools, it is given scant attention, if any, in the curriculum. As a result, the co-operative model remains a‘hidden alternative’ for many students. In this article, we argue for a cross-disciplinary integration of the co‑operative model into introductory management courses. To show how such an integration is possible, we present the process by which a series of short educational videos on worker co‑operatives was created. We describe the different steps in creating this educational material, highlighting the collaboration between the academic and business communities in the creative process, and outline the advantages of the co-operative model for illustrating contemporary themes in various areas of management. In conclusion, this article offers a reflection on how an organisational model that at first glance appears ‘undervalued’ in the academy can prove to be a great resource for illustrating complex concepts, stimulating reflection, and initiating discussions on ‘alternative’ models.

Foundations of Data Availability Sampling
Authors: Hall-Andersen Mathias , Simkin Mark , Wagner Benedikt
Published: January 2025

Towards building more scalable blockchains, an approach known as data availability sampling (DAS) has emerged over the past few years. Even large blockchains like Ethereum are planning to eventually deploy DAS to improve their scalability. In a nutshell, DAS allows the participants of a network to ensure the full availability of some data without any one participant downloading it entirely. Despite the significant practical interest that DAS has received, there are currently no formal definitions for this primitive, no security notions, and no security proofs for any candidate constructions. For a cryptographic primitive that may end up being widely deployed in large real-world systems, this is a rather unsatisfactory state of affairs.

In this work, we initiate a cryptographic study of data availability sampling. To this end, we define data availability sampling precisely as a clean cryptographic primitive. Then, we show how data availability sampling relates to erasure codes. We do so by defining a new type of commitment schemes which naturally generalizes vector commitments and polynomial commitments. Using our framework, we analyze existing constructions and prove them secure. In addition, we give new constructions which are based on weaker assumptions, computationally more efficient, and do not rely on a trusted setup, at the cost of slightly larger communication complexity. Finally, we evaluate the trade-offs of the different constructions.
Haven++: Batched and Packed Dual-Threshold Asynchronous Complete Secret Sharing with Applications
Authors: Alhaddad Nicolas , Varia Mayank , Yang Ziling
Published: January 2025

Asynchronous complete secret sharing (ACSS) is a foundational primitive in the design of distributed algorithms and cryptosystems that require confidentiality. ACSS permits a dealer to distribute a secret to a collection of N servers so that everyone holds shares of a polynomial containing the dealer's secret.

This work contributes a new ACSS protocol, called Haven++, that uses packing and batching to make asymptotic and concrete advances in the design and application of ACSS for large secrets. Haven++ allows the dealer to pack multiple secrets in a single sharing phase, and to reconstruct either one or all of them later. For even larger secrets, we contribute a batching technique to amortize the cost of proof generation and verification across multiple invocations of our protocol.

The result is an asymptotic improvement in the worst-case amortized communication and computation complexity, both for ACSS itself and for its application to asynchronous distributed key generation. Our ADKG based on Haven++ achieves, for the first time, an optimal worst case amortized communication complexity of κN without a trusted setup. To show the practicality of Haven++, we implement it and find that it outperforms the work of Yurek et al. (NDSS 2022) by more than an order of magnitude when there are malicious, faulty parties.
Simulation-Secure Threshold PKE from LWE with Polynomial Modulus
Authors: Micciancio Daniele , Suhl Adam
Published: January 2025

In LWE based cryptosystems, using small (polynomially large) ciphertext modulus improves both efficiency and security. In threshold encryption, one often needs simulation security: the ability to simulate decryption shares without the secret key. Existing lattice-based threshold encryption schemes provide one or the other but not both. Simulation security has seemed to require superpolynomial flooding noise, and the schemes with polynomial modulus use Renyi divergence based analyses that are sufficient for game-based but not simulation security.

In this work, we give the first construction of simulation-secure lattice-based threshold PKE with polynomially large modulus. The construction itself is relatively standard, but we use an improved analysis, proving that when the ciphertext noise and flooding noise are both Gaussian, simulation is possible even with very small flooding noise. Our modulus is small not just asymptotically but also concretely: this technique gives parameters roughly comparable to those of highly optimized non-threshold schemes like FrodoKEM. As part of our proof, we show that LWE remains hard in the presence of some types of leakage; these results and techniques may also be useful in other contexts where noise flooding is used.

We introduce a novel composition method that combines linear feedback registers into larger nonlinear structures and generalizes earlier methods such as cascade connections. We prove a Chaining Period Theorem which provides the cycle structure of these register constructions. We then use this Chaining Period Theorem and a new construction we call a Product Register (PR) to introduce a flexible and scalable register family with desirable properties, which we term Composite Mersenne Product Registers (CMPRs). We provide an algorithm to estimate the linear complexity of a chosen CMPR and investigate the statistical properties and security of a CMPR-based pseudorandom generator. Finally, we propose a family of CMPR-based stream ciphers and provide comparisons with the TRIVIUM stream cipher in terms of hardware area and security.
HELP: Everlasting Privacy through Server-Aided Randomness
Authors: Dodis Yevgeniy , Guan Jiaxin , Hall Peter , Lin Alison

Everlasting (EL) privacy offers an attractive solution to the Store-Now-Decrypt-Later (SNDL) problem, where future increases in the attacker's capability could break systems which are believed to be secure today. Instead of requiring full information-theoretic security, everlasting privacy allows computationally-secure transmissions of ephemeral secrets, which are only "effective" for a limited periods of time, after which their compromise is provably useless for the SNDL attacker.

In this work we revisit such everlasting privacy model of Dodis and Yeo (ITC'21), which we call Hypervisor EverLasting Privacy (HELP). HELP is a novel architecture for generating shared randomness using a network of semi-trusted servers (or "hypervisors"), trading the need to store/distribute large shared secrets with the assumptions that it is hard to: (a) simultaneously compromise too many publicly accessible ad-hoc servers; and (b) break a computationally-secure encryption scheme very quickly. While Dodis and Yeo presented good HELP solutions in the asymptotic sense, their solutions were concretely expensive and used heavy tools (like large finite fields or gigantic Toeplitz matrices).

We abstract and generalize the HELP architecture to allow for more efficient instantiations, and construct several concretely efficient HELP solutions. Our solutions use elementary cryptographic operations, such as hashing and message authentication. We also prove a very strong composition theorem showing that our EL architecture can use any message transmission method which is computationally-secure in the Universal Composability (UC) framework. This is the first positive composition result for everlasting privacy, which was otherwise known to suffer from many "non-composition" results (Müller-Quade and Unruh; J of Cryptology'10).
Round-Optimal Compiler for Semi-Honest to Malicious Oblivious Transfer via CIH
Authors: Madathil Varun , Scafuro Alessandra , Verber Tanner
Published: January 2025

A central question in the theory of cryptography is whether we can build protocols that achieve stronger security guarantees, e.g., security against malicious adversaries, by combining building blocks that achieve much weaker security guarantees, e.g., security only against semi-honest adversaries; and with the minimal number of rounds. An additional focus is whether these building blocks can be used only as a black-box. Since Oblivious Transfer (OT) is the necessary and sufficient building block to securely realize any two-party (and multi-party) functionality, theoreticians often focus on proving whether maliciously secure OT can be built from a weaker notion of OT.

There is a rich body of literature that provides (black-box) compilers that build malicious OT from OTs that achieve weaker security such as semi-malicious OT and defensibly secure OT, within the minimal number of rounds. However, no round-optimal compiler exists that builds malicious OT from the weakest notion of semi-honest OT, in the plain model.

Correlation intractable hash (CIH) functions are special hash functions whose properties allow instantiating the celebrated Fiat-Shamir transform, and hence reduce the round complexity of public-coin proof systems.

In this work, we devise the first round-optimal compiler from semi-honest OT to malicious OT, by a novel application of CIH for collapsing rounds in the plain model. We provide the following contributions. First, we provide a new CIH-based round-collapsing construction for general cut-and-choose. This gadget can be used generally to prove the correctness of the evaluation of a function. Then, we use our gadget to build the first round-optimal compiler from semi-honest OT to malicious OT.

Our compiler uses the semi-honest OT protocol and the other building blocks in a black-box manner. However, for technical reasons, the underlying CIH construction requires the upper bound of the circuit size of the semi-honest OT protocol used. The need for this upper-bound makes our protocol not fully black-box, hence is incomparable with existing, fully black-box, compilers.
Masked Computation of the Floor Function and Its Application to the FALCON Signature

Published: January 2025

FALCON is a signature selected for standardisation of the new Post-Quantum Cryptography (PQC) primitives by the National Institute of Standards and Technology (NIST). However, it remains a challenge to define efficient countermeasures against side-channel attacks (SCA) for this algorithm. FALCON is a lattice-based signature that relies on rational numbers, which is unusual in the cryptography field. Although recent work proposed a solution to mask the addition and the multiplication, some roadblocks remain, most noticeably, how to protect the floor function. In this work, we propose to complete the first existing tests of hardening FALCON against SCA. We perform the mathematical proofs of our methods as well as formal security proofs in the probing model by ensuring Multiple Input Multiple Output Strong Non-Interference (MIMO-SNI) security. We provide performances on a laptop computer of our gadgets as well as of a complete masked FALCON. We notice significant overhead in doing so and discuss the deployability of our method in a real-world context.
On the Key-Commitment Properties of Forkcipher-based AEADs
Authors: Rahman Mostafizar , Kundu Samir , Isobe Takanori
Published: January 2025

Forkcipher-based AEADs have emerged as lightweight and efficient cryptographic modes, making them suitable for resource-constrained environments such as IoT devices and distributed decryption through MPC. These schemes, including prominent examples like Eevee (Jolteon, Espeon, and Umbreon), PAEF, RPAEF, and SAEF, leverage the properties of forkciphers to achieve enhanced performance. However, their security in terms of key commitment, a critical property for certain applications such as secure cloud services, as highlighted by Albertini et al. (USENIX 2022), has not been comprehensively analyzed until now.

In this work, we analyze the key-commitment properties of forkcipher-based AEADs. We found that some of the forkcipher-based AEAD schemes lack key-commitment properties, primarily due to the distinctive manner in which they process associated data and plaintext. For two different keys and the same nonce, an adversary can identify associated data and plaintext blocks that produce identical ciphertext-tags with a complexity of

. Our findings apply to various forkcipher-based AEADs, including Eevee, PAEF, and SAEF, and naturally extend to less strict frameworks, such as CMT-1 and CMT-4.

These findings highlight a significant limitation in the robustness of forkcipher-based AEADs. While these modes are attractive for their lightweight design and efficiency, their deployment should be restricted in scenarios where explicit robustness or key-commitment security is required.
Zero-Knowledge Proofs of Quantumness
Authors: Phan Duong , Wen Weiqiang , Yan Xingyu , Zheng Jinwei
Published: January 2025

With the rapid development of quantum computers, proofs of quantumness have recently become an interesting and intriguing research direction. However, in all current schemes for proofs of quantumness, quantum provers almost invariably face the risk of being maliciously exploited by classical verifiers. In fact, through malicious strategies in interaction with quantum provers, classical verifiers could solve some instances of hard problems that arise from the specific scheme in use. In other words, malicious verifiers can break some schemes (that quantum provers are not aware of) through interaction with quantum provers. All this is due to the lack of formalization that prevents malicious verifiers from extracting useful information in proofs of quantumness.

To address this issue, we formalize zero-knowledge proofs of quantumness. Intuitively, the zero-knowledge property necessitates that the information gained by the classical verifier from interactions with the quantum prover should not surpass what can be simulated using a simulated classical prover interacting with the same verifier. As a result, the new zero-knowledge notion can prevent any malicious verifier from exploiting quantum advantage. Interestingly, we find that the classical zero-knowledge proof is sufficient to compile some existing proofs of quantumness schemes into zero-knowledge proofs of quantumness schemes.

Due to some technical reason, it appears to be more general to require zero-knowledge proof on the verifier side instead of the prover side. Intuitively, this helps to regulate the verifier's behavior from malicious to be honest-but-curious. As a result, both parties will play not only one role in the proofs of quantumness but also the dual role in the classical zero-knowledge proof.

Specifically, the two principle proofs of quantumness schemes: Shor's factoring-based scheme and learning with errors-based scheme in [Brakerski et al, FOCS, 2018], can be transformed into zero-knowledge proofs of quantumness by requiring an extractable non-interactive zero-knowledge argument on the verifier side. Notably, the zero-knowledge proofs of quantumness can be viewed as an enhanced security notion for proofs of quantumness. To prevent malicious verifiers from exploiting the quantum device's capabilities or knowledge, it is advisable to transition existing proofs of quantumness schemes to this framework whenever feasible.
