In recent years, the studies of blind signatures achieved a lot of results, but there still are many problems. Boneh and Boyen gave a new signature, derived the blind signature scheme from their idea. This paper first gave a blind signature without random oracles, with this property, the scheme was secure in standard model. Then, used common reference string to do non-interactive zero knowledge proof, made the blind signature into only two moves to achieve round optimal, and the concurrency operation of blind signature could be reach by this. For the algorithm is simple and not complicated, the blind signature is more efficient than the existing secure blind signature schemes,so save transmission bandwidth and improves transfer efficiency.
