Abstract

This paper illustrates how a transformation technique can be used to demonstrate therelationship among e-voting, e-auction, e-cheque, and e-cash, even though they serve distinct purposes.Initially, we examine the definitions of e-cheque and e-cash schemes, along with their respective securitymodels. Subsequently, we develop a systematic framework to transform e-cheque into e-cash, supportedby formal proof demonstrating the security of the conversion. As a corollary, we further exemplify thisintegration with a generic transformation framework to obtain e-cash from e-voting directly by combiningan existing transformation of e-voting into e-cheque and the transformation of e-cheque into e-cash whichwe established earlier. We apply our transformation framework to Li et al.’s transformed e-cheque schemeand Li et al.’s e-voting scheme to obtain a concrete, secure e-cash scheme that is IND-CCEA, IND-CIA, andEUF-CIA as an instance. Finally, we examine how our result contributes to the integration and relationshipbetween e-voting, e-auction, e-cheque, and e-cash systems.
