Research and Application of SNSV!Pv3 Security Mechanism In Electricity Network Management System

摘要

The safety of the electricity network management system has become the important issue of concern by people today. SNMPv3 increased the security management mechanism on the basis of vl and v2c, can resist the massage tampering, data intercepted, and other network security attacks effectively, ensured the reliability of network management better. This paper studies the modular frame structure of SNMPv3, introduces a new message structure and messages interaction process, shows the process of message handling based on USM(user-based security model). Finally, the USM is implemented in the actual electricity network management.
