Abstract

This paper presents the results of the comparative analysis of safety statistics and performance of encryption, the Strumok stream symmetric cipher (proposed for the national encryption standard of Ukraine) with other known cryptographic transformation algorithms, such as SALSA20, SNOW2.0, HC, AES with usages in stream mode, etc. They are accepted as national, international standards or are presented by the New European Schemes for Signatures, Integrity, and Encryptions (NESSI), Cryptography Research and Evaluation Committees (CRYPTREC) and others. The result of safety statistics is an analysis of the cryptographic properties of the output sequences using statistical test sets developed by the National Institute of Standards and Technology (NIST STS) and the DIEHARD tests. The result of the study of performance is the evaluation of the use of central processing unit (CPU) time to convert one octet of data to 64-bit computing platforms, following the test profile used in the eSTREAM contest.

Highlights

Today, due to intensive development and improvement of technology, society has more opportunities for social interaction, processing, and transmission of information that can serve the interests of individuals, corporations or states.in today's world, knowledge in various fields of activity and a person’s life plays an important role that requires multiple means of protection, provided service privacy policy in information and telecommunication systems.Currently, in cryptography, there are several groups of cryptographic transformations, namely, symmetric and asymmetric encryption
One of the critical indicators of stream ciphers is cryptographic resistance – a maximum period generating pseudorandom sequences, as the availability period of a pseudorandom sequence is a significant drawback to the statistical random sequences
The symmetric stream ciphers play an essential role in the processes of cryptographic protection of information
