| 摘 要： | 利用哈希函数、双线性对和相关数学困难问题等内容，提出一种基于身份的广义签密方案。方案中，用户的公钥利用用户身份信息计算而得，用户私钥由私钥产生中心PKG计算而得，方案三种模式的切换可分别实现签密、签名和加密的功能。最后对所提出的方案进行了安全性分析，分析表明，所提出的方案安全可靠且有效。

| Abstract: | With the content of hash function,bilinear pairings and related mathematical difficult problems,an ID-based signcryption generalized scheme was proposed.In the proposed scheme,users’ public keys were computed with the information of users’ identifies and users’ private keys were generated by Private Key Generator(PKG).Modes switching can perform different functions among three modes of signcryption,signature and encryption.The security of the proposed scheme was analyzed.The result shows that the proposed scheme is secure,reliable and efficient. |
