摘　　要：随着网络的不断发展,网络安全的问题日益突出。自从SNMPv3规范提出后,SNMP的安全性得到了很好的提高,使得SNMP能够更有效地对网络进行控制和管理。首先,提出SNMP网络管理存在的安全隐患,介绍了SNMPv3的框架和消息格式,针对SNMP存在的不足介绍了SNMPv3的基于用户的安全模型和基于视图访问控制模型,并详尽讨论了SNMPv3的认证、时限、保密、访问控制等安全服务机制,最后提出SNMPv3存在的问题。With the development of Internet, the safety of Internet has become one of the important issues. After the criterion of SNMPv3 is put forward, the safety of SNMP has highly improved. Now SNMP can control and manage network more effectively. Firstly, puts forward the security threats to network management with SNMP, and introduces the frame and format of the message of SNMPv3,then introduces the User- based Security ModeI（USM） and View- based Access Control Model （VACM） for SNMPv3 on these drawbacks,discussing the security mechanism for SNMPv3,such as authentication, time limit, privacy and access controlled in details. Finally puts forward the problem of SNMPv3 in existence.
