| 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.笔者构造了1个可高效撤销的无需安全信道带关键字搜索公钥加密方案.在该方案中,实际更新的数量仅为关键字陷门数量的对数级,这使得它非常实用.

| Abstract: | Any setting,PKI- or identity-based,must provide a means to revoke users from the system. Efficient revocation is a well-studied problem in the traditional PKI or identity-based setting. This paper proposes revocable secure channel free public key encryption with keyword search scheme. In the scheme,the actually updated-keywords number is only the logarithm of the number of users, which makes it very practical. |
