摘要
分析了大规模接入汇聚路由器(ACR)网管系统在用户密钥管理和消息交换传输中存在的安全问题,对SNMPv3中基于用户的安全模型(USM)以及非对称公钥密码机制进行了研究,提出了在SNMPv3中引入基于非对称公钥密码机制的PKSM安全模型以扩充USM的方法,增强了ACR网管系统对用户加密密钥更新与消息加密交换的整体安全性。
The problems of ACR network management system keys＇ s updating and management and messages exchanging are analyzed firstly. The user based on security model in SNMPv3 and the public key cryptography are studied secondly. Finally, a way of importing the public-key based on security model into the SNMPv3 standard framework is presented to enable the safety of updating the users＇ keys and the exchange of messages in ACR.
