Abstract: 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.
