Abstract

ABSTRACT
Mobile agent and digital coin represent two growing technologies in E-Commerce
systems. However, mobile agent systems suffer problems of cloning agents and the
inability to detect the user who cloned the agent. While digital coin suffers a problem of
spending the same coin more than once i.e. double spending. Merging these two
technologies into one scheme may solve such arising problems. Lam-Wei’s Scheme [1]
proof that the double spending detect-and-accuse cloning algorithm in e-cash can be used
to detect-and accuse cloning offenders. The presented paper follows an opposite approach
to this scheme as it implements a digital coin as mobile agent using some cryptographic
concepts. This proposed scheme implements an E-cash system that prevents the double
spending problem.
