An Efficient Threshold Blind Signature from Weil Pairing

摘要

Threshold blind signature is playing an important role in cryptography as well as in practical applications such as e-tash and e-voting systems, etc. In this paper, we present an efficient and praetical threshold bind signature from Weil pairing on super-singular elliptie curves or hyper-elliptic curves over finite field and prove that our scheme is provably secure in the random oracle model.
