摘　　要：量子计算机的发展使得传统公钥加密系统不再具有足够的安全性,研究抗量子的签名方案迫在眉睫,而格基签名可以满足这一需要。数字货币系统的出现使得盲签名得到了更多的关注,主要应用于匿名认证、电子投票等。通过对qTESLA方案以及RBS方案的研究和分析,给出一个基于格的盲签名方案,安全性基于RLWE问题以及RSIS问题的困难性,并证明了方案的盲性和one-more不可伪造性。The development of quantum computer makes the traditional public key encryption system no longer provide enough security.Research on quantum-resistant signature schemes is urgent,and lattice-based signature can meet this need.With the emergence of digital currency system,blind signature attracts more attention,and it is mainly used in anonymous authentication and e-voting.In this paper,through the research and analysis of the qTESLA scheme and the RBS scheme,we gave a blind signature scheme based on lattice.The security was based on the difficulty of the RLWE problem and the RSIS problem,and the blindness and one-more unforgeability of the scheme was proved.
