Randomization Enhanced Blind Signature Schemes Based on RSA

In this letter, we show that Fan-Chen-Yeh’s blind signature scheme and Chien-Jan-Tseng’s partially blind signature scheme are vulnerable to the chosen–plaintext attack. We also show that both schemes can be modified so that the chosen– plaintext attack is impossible. But, still Chien-Jan-Tseng’s partially blind signature scheme is vulnerable. It fails to satisfy the partial blindness property. ...

An efficient blind signature scheme based on the elliptic curve discrete logarithm problem

Elliptic Curve Cryptosystems (ECC) have recently received significant attention by researchers due to their high performance such as low computational cost and small key size. In this paper a novel untraceable blind signature scheme is presented. Since the security of proposed method is based on difficulty of solving discrete logarithm over an elliptic curve, performance of the proposed scheme ...

The new protocol blind digital signature based on the discrete logarithm problem on elliptic curve

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...
