    Testing of the Random Codes Generator of Embedded Crypto Protection System
    (Видавництво Львівської політехніки, 2022-02-28) Bilenko, V.; Rahma, R. M. K.; Hlukhov, V.; Lviv Polytechnic National University; The Iraqi Engineers’ Union
    The goal of the publication is to test the random codes generator of the built-in crypto-protection system Following the list of critical technologies in the production of weapons field and military equipment (following the Decree of the Cabinet of Ministers of Ukraine dated 30.08.2017 No. 600-r), an embedded microcontroller system for the protection of information for on-board equipment has been developed. A valuable stage of the system introduction is its research and testing. One of the stages of testing is the verification of the generator of random codes to use for the generation of encryption keys and digital signatures. Based on the previous works and research of the Kalyna algorithm, methods and tools for creating a random code generator have been studied to use in the built-in cryptographic data protection system for data encryption/ decryption and for working with a digital signature. Means of checking generated random codes and comparing themwith existing counterparts have been developed. The purpose of this article is to check the generator of random codes before using it in the built-in information protection system.

    Satellite scientific data collection and accumulation system as a basis for cyber-physical systems construction
    (Publishing House of Lviv Polytechnic National University, 2016) Hlukhov, Valerii; Lukenyuk, Adolf; Shenderuk, Sergii; Lviv Polytechnic National University; Lviv Centre of Institute for Space Research of National Academy of Sciences and the State Space Agency of Ukraine
    The paper reviews technologies of computer systems the development of which has led to the emergence of cyber-physical systems – there are embedded computer systems, open systems interconnection model, multilayer computer systems, wireless communications, microelectromechanical systems, data protection technologies. It is noted that there are computer systems exist, whose parameters are close to those of cyber-physical systems ones, there are also groups of developers who have experience of in such systems designing. The satellite scientific data collection and accumulation system developed in Lviv Center of Institute for Space Research of NAS and SSA of Ukraine with the participation of Lviv Polytechnic National University Computers department is an example of such systems. In paper The main features of this system are described in the paper. The recommendations are given onf using it as the basis for the creation of advanced cyber-physical systems.
