摘要：Electronic cash (or e-cash) research has been going
on for more than three decades since it was first proposed. Various
schemes and methods are proposed to improve privacy and security
in e-cash, but there is one security issue that less discussed
mainly in offline e-cash, namely, double-spending. Generally, the
mechanism to deal with double-spending in offline e-cash is
performing double-spending identification when depositing the
coin. Even though the mechanism is successful in identifying
double-spender, but it cannot prevent double-spending. This
paper proposes the Mobile Agent Platform based Wallet (MAPW)
to overcome the double-spending issue in offline e-cash. MAPW
uses the autonomy and cooperation of agents to give protection
against malicious agent, counterfeit coin and duplicate coin. This
model has been verified using Colored Petri Nets (CPN) and
has proven to be successful in preventing double-spending, and
overcoming malicious agent, and counterfeit coins.
