SNMP v3的安全机制综述

摘要

As a mainstream protocol in network management,SNMP has some obvious deficiency in security aspect,both in version v1 and v2.The problem is resolved effectively and reliably until the 3rd version is proposed,by introducing security model.In this paper,the security mechanisms of all the versions are discussed and contrast,in order to give readers a clear and comprehensive understanding.%SNMP是一种简单的网络管理协议,SNMP v1和SNMP v2,有比较明显的安全性缺陷。直到SNMP v3,才实现了一个有效可靠的安全模型。论文通过对比SNMP v1、SNMPv2和SNMP v3的安全机制,总结了各版本协议的安全性能,以帮助人们理解SNMP协议的工作原理和安全机制。
