Abstract
Threshold digital signature and blind signature are playing important roles in cryptography as well as in practical applications such as e-cash and e-voting systems, etc. In this paper, we present a new threshold blind digital signature based on pairings without the third party. Our scheme operates on Gap Deffie-Hellman (GDH) group, where Computational Diffie-Hellman problem is hard but Decision Diffie-Hellman problem is easy. For example, we use pairings that could be built from Weil pairing or Tate pairing. We also analyze security and efficiency of the scheme.
