Private key updating scheme of identity-based public key cryptography under distributed network
分布式网络中基于IDPKC的私钥更新方案

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.
