Design and Implementation of Cryptographic and Certificate Authority Center for User in VoIP System VoIP系统中用户加密认证中心的构建及实现
In this cryptographic mechanism, the private key of each user is consisted with a partial private key and a secret value chosen by themselves. The partial private key is generated by a partial trusted key generation center. 在无证书公钥密码机制中,用户的私钥是由用户的部分私钥和用户自己选择的一个秘密值组成,其中部分私钥由一个半可信的密钥生成中心产生。
