Exploring hybrid encryption methods in blockchain networks

Abstract

The purpose of the study 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 that combines symmetric and asymmetric encryption was proposed. The object of the study is the process of data exchange between participants in the block-chain network. The subject of the study is cryptographic methods aimed at improving the security of information transmission. An analysis of crypto-graphic risks was carried out, typical vulnerabilities of data transmission in public blockchains were identified, in particular when exchanging keys and transferring confidential information to or outside the network consensus. The result of the study is the development of a solution for a secure data transmis-sion channel using hybrid encryption, which is adapted to the peculiarities of the blockchain environment.
