© 2017 IEEE. Mobile robotic systems became essential part of our daily life. They can interact with humans as valued helpers, sometimes in relatively sophisticated tasks, which makes it necessary to record as much information as possible about robotic device activities. But if common approaches are used for data fixation in storage system, some portions of the data can be lost due to network constraints and/or robotic device failures. The paper discusses the log service architecture that provides reliable log delivery to the central storage from distributed heterogeneous mobile robotic nodes. Proposed log system consists of logical entities performing log buffering at robotic nodes, log transfer and centralized log data storage. Variety of log data types, generated by robotic nodes, are discussed, as well as the peculiarities of data storage. The necessity of data transmission between nodes is emphasized and the log data transmission algorithm is described.

© 2021 IEEE.The article deals with the pseudorandom number generators exploration using graphical methods. In this paper, we defined the necessary tools for building graphical tests and consider the features of static and dynamic PRNG research methods. Also, a method presented for numerical sequences visual inspection based on the joint use of the methods considered in this paper. Additionally, we presented comparison of the stochastic transformations results exploration using static and dynamic methods. Finally, we outline ways to improve the stochastic transformations research quality.

© 2022 IEEE.The development of block cryptoalgorithms does not stand still. There are new architectures and increase of key information. But there is one primitive that will always be present in block cryptoalgorithms. This is a substitution table or S-box. At the same time, the development of cryptography also requires the improvement of S-box. The article discusses approaches to improve the S-box efficiency. The structure of the substitution table with a controlled operation logic is proposed. The effectiveness of the proposed approaches is assessed.

© 2019 IEEE The article is devoted to the issues of increasing the statistical safety of pseudo-random number generators by equalizing the properties of the generated sequences. The traditional generator structure assumes two stages: the first provides good statistical properties and a long period of the formed sequence, the second is responsible for unpredictability and cryptographic resistance. In this case, the second stage can lead to deterioration in the statistical properties of the sequence formed by the generator. An approach based on adding to the traditional two-stage generators architecture of third-stage is considered. A variant of the third stage construction is proposed. The possibilities of applying the proposed approach to improve the statistical properties of modern ciphers are described. The results of statistical properties researches of the generators with implemented third stage are given.
