摘要：

We propose a model for fair electronic cash issued by multiple banks for the first time, A scheme of electronic cash with multiple banks in which a user can be traced is presented by using the improved group signature scheme of Cam97[4] and the group blind signature scheme of Lys98[14]. A weakness in the design of withdrawal and payment protocols using the existing group signature schemes is pointed out with its reasons analysed.
