Efficient Threshold Partially Blind Signature Scheme
MA Dong-lan · Jisuanji gongcheng · 2012
In view of some inefficient MapToPoint hash functions are used in existing threshold signature schemes.which cause these schemes to be very difficult to avoid the threats because of the hash functions many times use in the cryptography.A new threshold partially blind signature from bilinear pairings is proposed which combines the threshold signature and partially blind signature together.Analysis result shows that the new scheme only needs efficient common hash functions,it can improve the efficiency of the scheme and meet the merits of threshold and partially blind signature.
