Cryptanalysis of a Fully Anonymous Group Signature with Verifier-Local Revocation from ICICS 2018

For group signatures with verifier-local revocation (\(\textsf {GS}\hbox {-}\textsf {VLR}\)), selfless-anonymity (SA), which only ensures the anonymity of a signature against an adversary not possessing the signing secret-keys for members who were involved in the generation of the challenge signature, is strictly weaker than the de facto standard anonymity notion, full-anonymity, where the adversary is allowed to corrupt all members. At ICICS 2018, Hou et al. delivered a lattice-based fully anonymous \(\textsf {GS}\hbox {-}\textsf {VLR}\) scheme (as one core building block for their semi-generic construction of hierarchical \(\textsf {GS}\hbox {-}\textsf {VLR}\)) based on the first lattice-based \(\textsf {GS}\) scheme introduced by Gordon et al. at ASIACRYPT 2010. In this paper, we demonstrate that their scheme does not consider the anonymity for revoked members (no matter the misbehaving members or the honest ones who voluntarily leave), an implicit requirement for \(\textsf {GS}\hbox {-}\textsf {VLR}\) in a real-life application. Subsequently, we provide a modification of their construction to fix the mentioned weakness.

The Effects of Twin Text Instruction with Different Readability Levels on EFL Children’s Reading Comprehension

In the present study, the i-1 method is applied to young EFL learners who have a low level of English proficiency as well as reading motivation. The experiment of twin-text instruction was conducted in a community English library center, AJU Good Dream Center, in Seoul, Korea. The participants of the experiment were 13 elementary school students who enrolled in an English reading program during the winter vacation. There were 9 female students and 4 male students, and their grades ranged from 1st to 6th. The whole experiment was conducted for fourteen sessions, where each session consisted of one pretest, twelve teaching sessions with 12 pairs of text sets about the same topic in the order of ‘i-1’ level non-fiction texts to ‘i+1’ level of fiction texts, and one posttest. The findings are as follows. First, the twin-text reading instruction had positive effects on young Korean EFL learners, especially when the i-1 method was applied to expository text to pair with narrative text. Statistical analyses demonstrated that the posttest scores are higher than the pretest scores after the twin-text instruction, and the positive effects were greater for those with a lower level reading comprehension ability. Also, the students agreed that the twin-text instruction is helpful for improving their reading comprehension ability, and those with a lower level of reading comprehension ability had a more positive evaluation of the twin-text instruction. These results suggest that the i-1 method in twin-text instruction can be a good solution to reduce inequality in English education.
The Ancient Greek Potter’s Wheel: Experimental Archaeology and Web Applications for Velocity Analysis

The potter’s wheel is central to the understanding of ancient technology, knowledge transfer, and social complexity. With scant evidence of potter’s wheels from antiquity, experimental projects with replica potter’s wheels can help researchers address larger questions on ceramic production. One such set of experiments, performed using the Ancient Greek wheel replica in Tucson modelled on Athenian and Corinthian iconographic evidence, provided useful insight into the qualitative experience of ancient potters. In past experiments, the quantitative analysis of the throwing sessions included data on wheel velocity which had been collected collected over large intervals, comprising entire stages of the throwing process. While this method provides an overview of rotational speed, a continuous velocity graph provides a clearer picture collected data on wheel velocity. To address this, we developed a web application (WheelVis; brandonneth.github.io/wheelvis) to aid in the velocity analysis of experimental potter’s wheels. Users provide a recording of the throwing session and while advancing through the recording, they mark points where the wheel has completed rotations. Using the time intervals between these points, the tool reconstructs a graph of the velocity of the wheel throughout the throwing session. This innovative application provides fast, fine-grained velocity information, and helps archaeologists answer questions about the physical properties of their experimental replicas or wheels used in traditional workshops. Future development of the application will include contextual partitions to allow users to split the throw into different stages, enabling further analysis into the throwing process. Moreover, intelligent error detection would notify users when a mark is likely to be made in error and allow them to correct their mistake.
Money Creation in Fiat and Digital Currency Systems

To support the understanding that banks' debt issuance means money creation, while centralized nonbank financial institutions' and decentralized bond market intermediary lending does not, the paper aims to convey two related points: First, the notion of money creation as a result of banks' loan creation is compatible with the notion of liquid funding needs in a multi-bank system, in which liquid fund (reserve) transfers across banks happen naturally. Second, interest rate-based monetary policy has a bearing on macroeconomic dynamics precisely due to that multi-bank structure. It would lose its impact in the hypothetical case that only one ('singular') commercial bank would exist. We link our discussion to the emergence and design of central bank digital currencies (CBDC), with a special focus on how loans would be granted in a CBDC world.
SECURITY AND PRIVACY METHODS IN DISTRIBUTED SYSTEMS.

Rapid technological developments and distributed systems have found their most significant expression in the field of communication and dissemination of information.This mass spread of communications through distributed systems such as: internet, intranet, web services, etc., has been influenced by a number of advantages that they present, which have to do with the ease, speed of communication, the ability to communicate in real time between two or more subjects that are located at great distances from each other, etc.Increasing use of computers, computer systems, and distributed systems has increased the potential risk of damage or misuse of data and computer systems.The dangers that exist are many where some are with minor consequences and some with major consequences, such as: viruses that delete or modify data in systems, gain access to personal computers and use them to attack others, theft of credentials or credit card data, etc. Unfortunately 100% security in a distributed system does not exist despite the measures that can be taken, but taking some security measures minimizes the risk.While in institutions and private companies the protection measures are greater due to the organization, technical structures or investments made for security systems, etc. and thus ensuring a certain level of security, ordinary citizens or users are the ones who are most exposed and must show personal care in their protection.Therefore, they should have basic knowledge about the methods of its preservation.In this paper, we first study the features and types of distributed systems, security methods through CAPTCHA systems, cryptography, firewalls, etc; DS access channels.As a conclusion, it is intended to build a program in Java, with NetBeans IDE environment that enables the encryption (encoding) of a file with the help of the symmetric encryption algorithm TEA, in this case the encryption of an image, its decryption and display after decryption.

The Analysis of Road Traffic Fatality Pattern for Selangor, Malaysia Case Study

Road traffic fatality is a burden towards low- and middle-income countries including Malaysia. Seeing that Selangor has the highest number of road traffic fatalities in Malaysia for the year 2019, therefore the state is selected as a case study. The aim of the article is 1) to understand the road traffic crash pattern and road traffic fatality pattern in Selangor 2) to determine the ability of 16 road traffic features in classifying road traffic fatality occurrence. The preliminary data screening shows that road traffic crash patterns and road traffic fatality patterns in Selangor have many similarities. However, both of them also have few dissimilarities such as crash time of occurrence, day of occurrence, number of vehicles involved in a crash, and type of vehicle first hit for the crash. Supervised machine learning algorithm in Orange data mining software was considered in this analysis. The analysed algorithms among others are neural network, random forest, decision tree, logistic regression, naïve Bayes, and support vector machine. Neural network was seen as the best algorithm to classify road traffic fatality occurrence with 97.0% classification accuracy outperform other algorithms. The result of the article can be used by the relevant traffic stakeholders to execute safety intervention in a more focused manner in Selangor to reduce the number of road traffic fatalities.
A Survey on Identification of Online Public Shaming Using Machine Learning Framework

Social Media Platforms involve not millions but billions of users around the globe. Interactions on these easily available social media sites like Twitter have a huge impact on people. Nowadays, there is undesirable negative impact for daily life. These hugely used major platforms of communication have now become a great source of dispersing unwanted data and irrelevant information, Twitter being one of the most extravagant social media platform in our times, the topmost popular microblogging services is now used as a weapon to share unethical, unreasonable amount of opinions, media. In this proposed work the dishonouring comments, tweets towards people are categorized into 9 types. The tweets are further classifies into one of these types or non-shaming tweets towards people. Observation says out of the multitude of taking an interested clients who posts remarks on a specific occasion, lions share are probably going to modify the person in question. Moreover, it is not the nonshaming devotee who checks the increment quicker but of shaming in twitter.
Impact of reverberation through deep neural networks on adversarial perturbations

The vulnerability of Deep Neural Network (DNN) models to maliciously crafted adversarial perturbations is a critical topic considering their ongoing large-scale deployment. In this work, we explore an interesting phenomenon that occurs when an image is reinjected multiple times into a DNN, according to a procedure (called reverberation) that has been first proposed in cognitive psychology to avoid the catastrophic forgetting issue, through its impact on adversarial perturbations. We describe reverberation in vanilla autoencoders and propose a new reverberant architecture combining a classifier and an autoencoder that allows the joint observation of the logits and reconstructed images. We experimentally measure the impact of reverberation on adversarial perturbations placing ourselves in a scenario of adversarial example detection. The results show that clean and adversarial examples – even with small levels of perturbation – behave very differently throughout reverberation. While computationally efficient (reverberation is only based on inferences), our approach yields promising results for adversarial examples detection, consistent across datasets, adversarial attacks and DNN architectures.
