摘要
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。现有的使用双线性对的自认证公钥签名的文献数量少,效率也有待进一步提高。为此使用双线性对,构造了一种高效的自认证公钥签名方案。分析表明,新方案不仅安全,而且其效率也优于已有文献。
In self-certified public key signature scheme,the tasks of verifying the authenticity of public key and validating the signature were 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.There are only a few self-certified public key signatures of which the efficiency needs to be improved.In this paper,an efficient self-certified public key si...
