A blind signature scheme based on ElGamal signature

This paper presents a new generalized blind signature scheme based on ElGamal (1985) signatures. This new scheme has a valuable property that assures that if a message is signed multiple times the corresponding signatures will be different. This adds to the anonymity of the blinded signatures. Public key cryptosystems are beneficial in encryption as well as signing which plays an essential role in electronic banking and financial transactions. The current research introduces a generalized signature scheme that could be used to generate blinded signatures as well as ordinary ElGamal signatures. The new scheme is found to be comparable to the RSA blinding. Moreover, the new scheme has the advantage of having less computational complexity and is faster than RSA in the blinding procedure
