In order to cope with the growing network threats,the information security and protection mechanism of power system communication network should be deeply studied.This paper analyzes in detail the structure,topology,protocols and standards of the power system communication network as well as the types and potential paths of malicious attacks,and proposes innovative security mechanisms in terms of authentication and authorization,encryption and decryption algorithms,application of security protocols,and network intrusion detection and defense.Implement and optimize the existing protection mechanism,and conduct experiments and case studies on network monitoring and logging,attack response and emergency response to verify its effectiveness in real scenes.The research results show that the proposed security mechanism can effectively improve the security prevention ability of power system communication network,effectively defend against all kinds of malicious attacks,and provide a strong guarantee for maintaining the stable operation of power system.
