Abstract: - Electronic cash (e-cash) has been more and more popular in the electronic commerce transaction protocol. Ronggong Song and Larry Korba present their views on e-cash to improve Abe and Fujisaki's protocol. Their protocol achieves non-repudiation and anonymity services between customer and merchant. However, there still has weak fairness in their protocol. Therefore, we propose a modified e-cash protocol to avoid weak fairness. The properties of our protocol include: (1) fair exchange for everyone that include in the protocol (2) anonymity for the customer and (3) non-repudiation for the customer, merchant and bank.
