A New Multi-Bank E-cash Protocol with Anonymity Control

摘要：

Most proposed multi-bank e-cash protocols in the literature have been developed based on group signatures in which the member revocation problem is inevitable. In this paper, we propose a new multi-bank e-cash protocol by using blind ring signatures and linkable ring signatures, by which the client anonymity control and bank anonymity control are achieved respectively.Since our blind ring signature scheme and linkable ring signature scheme are both based on XTR,we conclude that our protocol is secure and efficient.
