| 摘 要： | 通常的密码系统,IBE或者PKI都必须提供从系统中撤销用户私钥的途径,同样PEKS也应该提供撤销陷门的方式.本文研究了可高效撤销的无需安全信道的带关键字搜索公钥加密方案的形式化定义及安全模型.基于BDH问题,可证明方案的安全性.

| Abstract: | Any setting,Public-key Infrastructure or Identity-Based.Must provide a means to revoke users from the system.Efficient revocation is a well-studied problem in the traditional Public-Key Infrastructure or Identity-Based Encryption.We propose revocable public key encryption with Key words search scheme of formalized definition and the security model in the paper.Based on bilinear dilinear diffie-hellman,the security of the scheme can be proved. |
