摘  要:盲签名因其具有匿名性等特点,而具有广泛的应用领域和应用前景,根据盲化对象的不同划分为盲消息签名和盲参数签名。文章利用双线性对,提出了基于无证书的盲参数签名方案,方案的签名密钥由用户和密钥生成中心共同生成,防止签名伪造,同时解决了复杂的证书管理问题和密钥托管问题。

Abstract:Because of its anonymity,blind signature has a wide range of application fields and application prospects. It is divided into blind message signature and blind parameter signature according to different blind objects. Based on bilinear pairing,this paper proposes a certificate-free blind parameter signature scheme. The signature key of the scheme is jointly generated by the user and the key generation center to prevent signature forgery. At the same time,it solves complex certificate management problems and key escrow problems.

Keywords:certificate-free cryptosystem;blind signature;blind parameter signature;bilinear pairing
