| 摘 要： | 利用双线性群，在代理重签名机制和盲签名机制的基础上，提出了一个有效的无证书盲代理重签名方案。方案中解决了密钥托管问题及证书管理带来的额外开销，同时实现了代理者在签名转换中消息隐私特性。基于NGBDH问题和Many-NGBDH的困难性，证明了新方案具有能够抵抗伪造攻击的特性。该方案满足正确性和消息盲性。

| Abstract: | Using bilinear groups,an efficient certificate less blind proxy re-signature scheme was proposed based on the proxy re-signature scheme and blind signature scheme.The scheme solves the using of certificate in certificate-based scheme and removes key escrow in ID-based scheme.While achieving message privacy features of the proxy signature conversion.Based on the difficulty of NGBH and Many-NGBH problem,It proves that the new scheme can resist forgery attack characteristics.The scheme satisfies security properties:correctness and message blindness. |
