| 摘 要： | 为了解决密钥托管问题,Al-Riyami和Paterson提出了无证书签名方案.通过修改陆等人基于身份的一次代理签名方案密钥的产生算法,提出了无证书一次代理签名方案,并且正式定义了无证书一次代理签名方案的安全模型.在随机预言机模型下,证明方案的安全性依赖于CDH困难问题.

| Abstract: | To solve the key escrow problem, Al-Riyami and Paterson introduced the concept of certificateless signature scheme (CLS). This paper has proposed the certificateless one-time proxy signature scheme which modifying the key generation algorithms of Lu et al.'s ID-based one-time proxy signature scheme and formalized the security notions for certificateless one-time proxy signature scheme (CLOTPS) are formalized in this paper. The security of the proposed scheme is proved to be equivalent to the computational Diffie-Hellman (CDH) problem in the random oracle model. |
