中国政府发布了SM2数字签名算法作为中国公钥密码标准的一部分，现已成为国际标准算法。为了保护消息的隐私，本文提出了一种基于SM2签名算法的高效盲签名方案。我们证明我们的方案可以满足盲目性和EUF-CMA（选择消息攻击下的存在不可伪造性）。我们使用 MIRACL Cryptographic SDK 实现我们的方案，并提出一种变体盲签名方案。安全分析和实验评估表明我们提出的方案对于实际应用是实用的。
The Chinese government releases the SM2 digital signature algorithm as one part of the Chinese public key crypto standard, and now it has become an international standard algorithm. To protect the privacy of messages, we propose an efficient blind signature scheme based on the SM2 signature algorithm in this paper. We prove that our scheme can satisfy blindness and EUF-CMA (existential unforgeability under chosen message attacks). We implement our scheme using MIRACL Cryptographic SDK, and propose a variant blind signature scheme. Security analysis and experimental evaluation demonstrate that our proposed scheme is practical for real-world applications.
