Blind signature without random oracles
无随机预言模型的盲签名

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 bli...
