摘　　要：首先，提出了一种基于公钥自证明的认证加密方案。该方案采用用户注册协议动态地完成用户向CA的匿名身份注册，并获取由CA和用户共同产生的公钥的证明，据此可以计算用户的公开密钥；握手双方使用公钥的自证明协议，动态地完成对彼此公钥的自证明；信息的接收者可以从签名中恢复原消息，这样，签名方案既具有身份鉴别作用，又具有信息保密性。其次，利用本方案生成一个秘密握手协议。在秘密握手协议中，一个诚实的成员绝不会透露该组情形，除非其他组成员是本组的成员。如果双方通信失败，任何一方的身份将不会予以披露。First,a self-certified signature based on public key cryptosystem was proposed. In this scheme,a user anonymously fulfills identity registration with the protocol of user registration,and gets the certificate of public key generated from CA and the user. Based on this certificate,the public key of a user can be computed. The both end users of handshaking can finish the verification of public key for each other with the protocol of self-certified of public key. The receiver of message can recover the original message based on the signature. Therefore,the proposed signature scheme has identity authenticated and message confidentiality. Second,generates a secret handshake making use of a scheme.In a secret handshake protocol,an honest member in the group never reveals his group af?liation unless the other party is a valid member of the same group. If a handshake between two parties fails,the identity of either party is not disclosed.
