摘　　要：在盲签名方案中,消息和签名结果对签名人是不可见的。在自认证公钥签名中,验证签名有效性的同时,也验证了公钥的真实性。与已有的基于证书和基于身份的两种签名相比,自认证公钥体制具有通信代价低、计算量少的优点。结合盲签名和自认证公钥签名,使用双线性对,首次构造了一种高效的自认证公钥盲签名方案。分析表明,新方案不仅是安全的,而且其效率也非常高。In blind signature scheme,a message and the signature result can not be known by the signer.In self-certified public key signature scheme,the tasks of verifying the authenticity of public key and validating the signature are carried out simultaneously.The self-certified public key signature is more efficient than the existing certificate-based signature and identity-based signature in terms of communication overheads and computation efforts.In this paper,an efficient self-certified public key blind signature scheme is proposed firstly by using bilinear pairings and combining blind signature and self-certified public key signature. It is showed the proposed scheme is secure and efficient.
