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.
