Abstract :
In this paper, a online undividable electronic cash scheme based on Schnorr digital signature is proposed. In the scheme, we introduce an authentication method of the business behaviour by using a random number, which effectively guarantees the right of the two trade parts. With analyzing, we find our scheme has many secure characters, such as, anonymity, unforgeability, exemption from repetitious expenditure, etc.
