摘要: 部分盲签名通过在最终的签名数据中添加签名者和用户协商的公共信息,较好地解决了盲签名在匿名性和可控性之间的矛盾。基于Shim(SHIM K A. An ID-based aggregate signature scheme with constant pairing computations. The Journal of Systems and Software, 2010, 83(10): 1873-1880 )提出的基于身份的数字签名方案,提出了一个新的可证安全的基于身份的部分盲签名方案。在随机预言机模型下证明了新方案对自适应选择消息和身份攻击是存在不可伪造的,其安全性能够归约为计算Diffie-Hellman假设。与目前已有的随机预言机模型下基于身份的部分盲签名方案相比,所提方案具有较高的运算效率和较少的通信量。

Abstract: Partially blind signature allows signer to add some public information negotiated by signer and user to signature, and better solves the conflict between anonymity and controllability of blind signature. Utilizing the Shim's (SHIM K A. An ID-based aggregate signature scheme with constant pairing computations. The Journal of Systems and Software, 2010, 83(10): 1873-1880 )ID-based signature scheme, a new provable secure ID-based partially blind signature scheme was proposed. The scheme was proved to be existentially unforgeable against adaptive chosen message and identity attacks in random oracle model, and the security was reduced to computational Diffie-Hellman assumption. Compared with other ID-based partially blind signature schemes in random oracle model, the proposed scheme has better computational efficiency and less communication.

Key words: partially blind signature, bilinear pairing, ID-based, random oracle model, provable security
