提出了一个基于配对的高效的基于身份的签名方案，其安全性依赖于随机预言机模型下Diffie-Hellman问题的困难性。我们描述了如何获得这个计划作为一个特殊版本的一个更一般的通用计划，产生进一步的新的可证明安全的基于身份的签名方案，如果使用配对。通用方案还包括传统的公钥签名方案。我们更进一步。讨论密钥托管和将密钥分发给多个信任机构的问题。附录包含了超奇异椭圆曲线和Weil和Tate配对的相关性质的简要描述。
We develop an efficient identity based signature scheme based on pairings whose security relies on the hardness of the Diffie-Hellman problem in the random oracle model. We describe how this scheme is obtained as a special version of a more general generic scheme which yields further new provably secure identity based signature schemes if pairings are used. The generic scheme also includes traditional public key signature schemes. We further. discuss issues of key escrow and the distribution of keys to multiple trust authorities. The appendix contains a brief description of the relevant properties of supersingular elliptic curves and the Weil and Tate pairings.
