摘要:

提出了一种基于身份的公钥密码体制(IDPKC)的分布式网络私钥更新方案,新方案通过引入一个映射函数,将用户的更新请求均匀地分配在整个更新时段内,避免了更新请求的拥塞现象。并且进一步给出了新方案下用户私钥更新和会话密钥协商过程。通过分析,该方案能满足安全性要求,并且具有较好的扩展性。

Abstract:

A new private key updating scheme of IDPKC under distributed network was proposed. The new scheme allotted all updating requests to the entire updating period by introducing a mapping function, and avoided the congestion of updating requests. The paper also introduced the private key updating process and the session key agreement process under the new scheme. Analysis shows the new scheme can fulfill the security requirement and has high expansibility.
