Signal with Blake2, Chacha20 and Poly1305

Messaging applications are now adopting the concept of end to end encryption. Signal uses the Signal Protocol which has no known vulnerabilities for its end to end encryption. The protocol was explained in this work and possibilities of improvements were explored. It was discovered that the protocol implementation uses the SHA-512 hash, AES in CBC mode for encryption and HMAC for authentication. These Cryptographic Primitives were replaced with more efficient alternatives, Blake2, Chacha20 and Poly1305 respectively. An application was created to test the running time of the proposed cryptographic primitives against the existing one. From the results, Blake2b performs better than SHA-512 when hashing keys, short text, and 1.4 MB file. Similarly, Chacha20/Poly1305 performs better than AES/CBC/HMAC-sha256 in both encrypting and decrypting short text as well as 1.4 MB file. The proposed changes were implemented in the Signal Application. Automatic test in the Signal application was used to ensure that changes made to the code did not cause any logic errors. To further test the application, it was installed on another phone and messages were sent. The security code was also verified. . Keywords: Signal, Blake2, Chacha20, Poly1305

Information Crimes in the Structure of Russian Extremist and Terrorist Criminal Practice

The presented article is intended to determine the share of information crimes in the чstructure of Russian extremist and terrorist criminal practice and, as a consequence, to propose efficient methods of countering information crimes specifically for combating these crimes in general. The solution to this problem is implemented by applying statistical analysis of official data on criminality metrics supported by legal hermeneutics and sociological methods, combined with a historical approach to the subject. It is discovered that modifications in the legal regulation of information crimes in the Criminal Code have largely led to changes in the number of registered extremist and terrorist crimes in general. The article reveals a significant share of information crimes in the structure of extremist activity. Even after a decrease in 2019, it still accounts for about a third of all extremist crimes. In the structure of terrorist activity about every 10th terrorist crime is an information crime. In the extremist criminal activity and approximately in a half of all terrorist crime cases, illegal information is generally disseminated through the Internet. In approximately 75 % of cases, the extremist or terrorism-related information is disseminated in the Internet by people aged under 30 years old. The vast majority of all convicts are unemployed people without higher education. The system for preventing dissemination of extremist and terrorist information should be retargeted to improve the legal culture, including the value of each social group, as well as the Internet communication culture

Dimensions of Space

The existence and the mysteries of the universe could not be explained by using just 3 spatial dimensions. There was a need to think of higher dimensions as a tool to explain the phenomena happening in our universe. Therefore, unified theories such as Loop Quantum Gravity and Superstring Theory were proposed. We will be taking an overview of these theories in order to get some idea about each.
The implementation of Guessing Game technique in teaching speaking

Capability of speaking in English has necessarily become the need of the students of senior high school. However, the majority of the students have low capability of speaking. This was due to a number of factors, one which was the inappropriate use of the method the teacher used in the classroom. The guessing game technique was beloved to have enabled students to improve their speaking capability. The current research aimed to investigate i) the significant improvement of the students’ speaking ability after the implementation of the guessing game technique, ii) the effect of the guessing game technique on the students’ capability in every single aspect of speaking and, iii) the correlation between the students’ attitudes and their speaking achievement. The subjects of the research were 35 students at SMAN 1 Sidomulyo. There were three raters who assessed students’ speaking ability. The data were collected trough the tests (pre-test and post-test) and questionnaires. Furthermore, the Repeated measure t-test was used to analyze the data collected from both the pre and the post tests. While, the data from questionnaires were analyzed by using Pearson product moment. The results showed that the guessing game technique has a statistically significant effect on the students’ speaking ability with the significant level 0.05. Moreover, there was correlation between the students’ attitudes and their speaking achievement. This suggests that the guessing game technique facilitates students to improve their capability of speaking. Keywords: speaking, guessing game technique, descriptive text, attitude
A Comparison Study of Goodness of Fit Tests of Logistic Regression in R: Simulation and Application to Breast Cancer Data

Goodness of fit (GOF) tests of logistic regression attempt to find out the suitability of the model to the data. The null hypothesis of all GOF tests is the model fit. R as a free software package has many GOF tests in different packages. A Monte Carlo simulation has been conducted to study two situations; the first, studying the ability of each test, under its default settings, to accept the null hypothesis when the model truly fitted. The second, studying the power of these tests when assumptions of sufficient linear combination of the explanatory variables are violated (by omitting linear covariate term, quadratic term, or interaction term). Moreover, checking whether the same test in different R packages had the same results or not. As the sample size supposed to affect simulation results, so the pattern of change of GOF tests results under different sample sizes as well as different model settings was estimated. All tests accept the null hypothesis (more than 95% of simulation trials) when the model truly fitted except modified Hosmer-Lemeshow test in "LogisticDx" package under all different model settings and Osius and Rojek’s (OsRo) test when the true model had an interaction term between binary and categorical covariates. In addition, le Cessie-van Houwelingen-Copas-Hosmer unweighted sum of squares (CHCH) test gave unexpected different results under different packages. Concerning the power study, all tests had a very low power when a departure of missing covariate existed. Generally, stukel’s test (package ’LogisticDX) and CHCH test (package "RMS") reached a power in detecting a missing quadratic term greater than 80% under lower sample size while OsRo test (package ’LogisticDX’) was better in detecting missing interaction term. Beside the simulation study, we evaluated the performance of GOF tests using the breast cancer dataset.
