摘　　要：盲签名因其匿名性应用于电子商务、电子投票和匿名存取控制等领域。按照盲化对象的不同盲签名可划分为盲消息签名和盲参数签名。利用椭圆曲线上Weil配对的双线性性质,提出了基于身份的盲消息签名和盲参数签名方案,其安全性基于椭圆曲线上的离散对数难题和GDH难题。这些方案用以身份为基础的公钥取代以数字证书形式的公钥,简化了公钥的管理并节省了存储空间。The anonymity of blind signature scheme can be applied to the field of e - commerce, e - voting and anonymous access control and etc. Blind signature scheme can be classified into blind message signature and blind parameter signature in accordance with the different blinded object, which may be message to be signed or signature by the signer. By using the bilinear pairings, an ID - based blind message signature and ID - based blind parameter signature scheme are proposed, which is based on the discrete logarithm problem and gap diffie- hellman problem. These schemes use ID - based public key instead of public key of digital certification, can effectively simplify the procedure of public key management and reduce the disk storage space.
