摘　　要：无证书公钥密码体制和代理盲签名都因其自身的优点而成为当前学术界的研究热点,但是有的无证书的代理盲签名存在一定的安全漏洞,如攻击者能够恢复出私钥、跟踪签名信息等.本文结合代理签名和盲签名的优点,利用无证书公钥密码体制和双线性对构造了一个安全高效的代理盲签名方案.经过安全性分析,该方案满足代理盲签名的盲性、不可伪造性、可验证性、不可否认性等安全特性,能够应用于电子商务、电子政务等保护用户隐私且需要代理签名的场合,具有较高的执行效率.Certificateless public key cryptography and proxy blind signature have become the research focus in the academic circles because of their own advantages. But some certificateless proxy blind signature schemes have certain security holes, such as the private key restored by attackers, tracking signature information, etc. With the advantagement of proxy signature and blind signature, this paper structures a secure certificateless proxy blind signature scheme which makes use of certificateless public key cryptography and bilinear pairing. We can claim that it satisfies the security properties of both blind signatures and proxy signatures. This signature can be applied in the electronic commerce, electronic government affairs, ect where users privacy should be protected and need proxy sign.
