STABLE ENCRYPTION FUNCTION OF THE ADVANCED MODULE OF CRYPTOGRAPHIC PROTECTION OF INFORMATION IN INFORMATION AND COMMUNICATION SYSTEMS

The paper analyzes the requirements for the construction of data privacy systems based on cryptographic algorithms, identifies key aspects and ways to improve existing methods and systems of data encryption. Research methods. The main theoretical provisions of the work are obtained using the methods of information security theory. The object of research is the process of ensuring the confidentiality of data in information and communication systems management systems based on cloud technologies. The subject of the study is a stable encryption function to provide an advanced module of cryptographic protection of information in information and communication systems. The aim of this work is to develop a stable encryption function of the advanced module of cryptographic protection of information to ensure data confidentiality in information and communication systems management processes based on cloud technologies. A method of generating cryptographic keys was developed to improve the speed of key generation, using an encryption function (to provide an advanced module) based on the well-known and efficient RC6 algorithm, which increased the speed of cryptographic data processing and tes
