Abstract :

In recent years it has been trying that with regard to the question of computational complexity of discrete logarithm more strength and less in the elliptic curve than other hard issues, applications such as elliptic curve cryptography, a blind digital signature method, other methods such as encryption replacement DLP. In this paper, a new blind digital signature scheme based on elliptic curve cryptography system is proposed. The presented scheme, safe and efficient manner is able to meet the needs of a digital signature system meet the blind. Analysis and evaluation of the efficiency of the Protocol presented in comparison with that in the past has been raised, the superiority of the proposed method.
