利用双线性对技术构造了一个新的基于仲裁的身份签名方案.新方案解决了IBC系统中密钥的即时撤销问题,其安全性基于DH计算问题的困难性.与以往文献中提出的基于仲裁的身份签名相比,新方案实现了SEM对待签消息的完整性校验及对用户的认证,同时保护了待签消息的机密性,具有较高的应用价值.

A new Mediated Identity-Based Signature scheme from bilinear pairing achieving immedi-ately key revocation is presented. The security of the new scheme is based on computational Diffie-Hellman assumption. Compared with existed literature, the scheme can validate the integrality of message to be signed, authenticate the legality of uses and protect the confidentiality of the message.It is valuable.
