基于身份代理盲签名方案的密码学分析
Cryptanalysis of Identity-based Proxy Blind Signature Schemes
摘要
Abstract
Blindness, namely unlinkability, is an important property of blind signature. Zhang Xuejun analyzed identity-based proxy blind signature schemes proposed respectively by Cai Guangxing and Nong Qiang, pointed out that the two schemes did not satisfy blindness property and they were linkable, and proposed improved schemes with blindness. This paper researches Zhang Xuejun's linkability analysis to Cai Guangxing and Nong Qiang' schemes, finds that Zhang Xuejun's analysis method of linkability has drawbacks, and then uses construction method to prove that proxy signer can not use the parameters generated during the signing to track the signature. So Cai Guangxing and Nong Qiang' schemes still satisfy the blindness property and they are unlinkable.关键词
