Randomized Partially Blind Signature Scheme
MA Dong-lan · Jisuanji gongcheng · 2011
In view of the questions that the proposed partially blind signatures very little consider the randomization property,and also very little give any formal proofs.A provably secure randomized partially blind signature scheme based on bilinear pairing is presented.In the scheme,a method is used that the randomization parameter is decided by the random numbers chose by the signer and the signature receiver,and some formal proofs from correctness,randomization,unlinkabiliy and unforgeability of the scheme are given,which makes the scheme more security.
