Application of hybrid encryption methods in blockchain networks

Abstract

The purpose of the research is to implement hybrid encryption methods to ensure the confidentiality, integrity and authenticity of transmitted data in blockchain networks. Modern cryptographic algorithms were analyzed, their advantages and disadvantages were identified, and a hybrid scheme was proposed that combines symmetric and asymmetric encryption. The object of the research is the process of data exchange between participants in the blockchain network. The subject of the research is cryptographic methods aimed at increasing the security of information transmission. An analysis of cryptographic risks was conducted, and typical vulnerabilities of data transmission in public blockchains were identified, in particular when exchanging keys and transmitting confidential information to or beyond the network consensus. The result of the research is the development of a solution for a secure data transmission channel using hybrid encryption, adapted to the characteristics of the blockchain environment.
