The Application of Blockchain Technology in Network Information Security

Abstract

With the rapid development of the Internet, the problem of network information security has become increasingly prominent. The traditional network security solutions have the weaknesses of centralization and vulnerability to attack, and cannot effectively deal with the risk of attack and data tampering. As a decentralized and tamper-resistant distributed ledger technology, blockchain technology has a good potential to be applied to network information security protection. This paper aims to summarize the basic principle and security characteristics of blockchain technology, discuss the network information security protection method based on blockchain, and analyze the application of blockchain technology in identity protection, food supply chain, O2O catering and other aspects for reference.
