摘要
SNMPv3作为一种新的网管协议于1998年问世,网管的安全性是它重点关心的问题之一,其采用消息认证码、时间戳、加密手段和访问控制确保安全性。该文针对SNMPv3的安全性问题,描述了它的主要安全威胁,介绍它的各项安全机制,然后从算法、密钥管理等方面较详细分析它的安全性,指出了潜在的安全隐患和实现中需注意的问题,并提出相应的建议。
SNMPv3, tbe latest network management protocol, came into being in 1998. Security of network management is one of the main issues it cares. SNMPv3 employs MAC, time stamp, encryption and access control to secure network management. This paper describes its primary threats and introduces its security mechanisms. Then the paper analyzes security of SNMPv3 from different aspects such as algorithm and key management. Finally, the paper points out potential security problems and issues that need noticing in impl...
