A practical anonymous multi-authority e-cash scheme

摘要

We propose a practical multi-authority e-cash scheme that satisfies anonymity, security and verifiability. By means of our proposed scheme, the issue of c-coins is controlled by several issuers. Customers can request e-coins from several issuers, who represent a bank, on the current available issuers list according to the Internet condition. (C) 2002 Elsevier Inc. All rights reserved.
