Research on Security and Protection Strategy of Computer Data Based on Blockchain

Abstract

From the perspective of computer data security protection, this paper explores the application of block chain technology from three aspects: cryptography technology, secure communication technology, access restriction and technology, this paper analyzes the advantages of block chain technology in computer data security protection, in order to maximize the computer data security. In cryptography, algorithms such as symmetric encryption and public-key cryptography provide multiple guarantees for computer data security. The technology of access restriction includes object access restriction, security judgment and so on, which improves the effect of data security protection.
