Abstract

The paper is devoted to.the development of an encryption algorithm resistant to leakage through side channels The objectives of the work were the development and computational-experimental justification of the algorithm. Materials and methods. A new algorithm of encryption resistant to attacks through side channels is proposed.The algorithm resistance to attacks on the basis of numerical experiments is analyzed.As a result of analyzing statistical data before and after modifications of the algorithm it was found that the developed algorithm is resistant to time and energy attacks. Results of the study.The main result of the work is the development of an encryption algorithm resistant to attacks through side leakage channels. The resilience of the algorithm to attacks was confirmed by analyzing the statistical data before and after modifications to the algorithm. The comparisons concluded that the developed algorithm is resistant to timing attack and power consumption attack. Discussion and Conclusion. The resulting algorithm can be applied to counter groups of attacks on cryptographic devices, in which the attacker tries to obtain any information useful to him, through the physical features of the implemented cryptosystem.
