This paper combined the virtues of blind signature with ELGamal digital signature and designed a blind signature of electronic cash scheme based on improved ELGamal digital signature. Its security relied on discrete logarithm problem and also improved the security of electronic cash. With the detailed analysis of its security and efficiency,it not only had the features of strong anonymity,Unforgeability and no double spending,but also had a certain degree of theoretical and application value.
