The information security is playing an increasingly important role nowadays. Therefore, virus can be transmitted through the information in encrypted form. This is also applied to embedded systems. In this regard, the article is assigned to the topic of cryptocurrency protection in embedded systems using the national Ukrainian standard Kalyna. To further explore the topic, this algorithm was implemented on a microcontroller to test the performance, convenience and prospects for usage in embedded systems.

The information security is playing an incre- asingly important role nowadays. Therefore, virus can be transmitted through the information in encrypted form. This is also applied to embedded systems. In this regard, the article is assigned to the topic of cryptocurrency pro- tection in embedded systems. The article is focused on the algorithm of symmetric block transformation "Kalyna". The algorithm has been developed in cooperation with the State Special Communications Service and leading Ukrainian scientists. The experience and results of interna- tional and open national competition of cryptographic algorithms have been taken into account. The algorithm is intended for gradual replacement of the interstate standard DSTU GOST 28147: 2009. Its differences from other data encryption standards used, both in Ukraine and in the world, have been ana- lyzed. The stability of the "Kalyna" algorithm has been also analyzed using a high-bit key (512 bits) and its speed has been compared with other cryptographic protection algorithms.

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 them with 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.
