Ripeng Ren, Mingrui Ma, Wei Liu · 2023
Globally, problems such as computer viruses, network attacks, spam, system vulnerabilities, network theft, false and harmful information and network crimes are becoming increasingly prominent. If not handled properly, it may have adverse effects on China's economic and social development and national security. Therefore, the problem of computer network information security has become one of the problems that must be seriously faced and urgently solved. This paper studies network information security through SM2 algorithm. The principle of firewall software to protect big data information content is that the software can clearly distinguish the internal and external networks, which not only ensures the security of the computer's internal environment, but also reduces the possibility of external environment viruses invading the computer. The SM2 algorithm and blockchain technology are used to construct the optimal defense system of network information security, and a dynamic defense system of network information security based on unified security base, with security on-demand empowerment as the core, and intelligent security management as the guarantee is proposed, which can provide a reference for improving the security defense capability of China's network information system.
