new randomized partially blind signature scheme
Xinghua Zhang · Advances in computer science research · 2015
The existing partially blind signature schemes rarely consider the random,and had less strict proof on random.Based on bilinear pairings and elliptic curve discrete logarithm problem,this article proposes a new randomized partially blind signature scheme.The random parameters jointly generated by the signer and the signature receiver who selectes random number in this scheme.It is proved that the scheme satisfies unforgeability, partial blindness, effective against other people in the public information substitution attack.
