This paper proposes an extension of the Digital Value Exchange Protocol that enables fair exchange of digital values, e.g., electronic money and digital tickets, over a P2P system without requiring the use of an external negotiation facility. The digital values stored in the partners' smart cards are exchanged through the network using 4 message exchanges based on the Optimistic Fair Exchange Protocol; digital values are directly exchanged between a pair of users; the Trusted Third Party(TTP) is accessed to resolve the conflict only if this exchange is interrupted. Traditionally, the partners and the exchanged digital values are determined by external negotiation before the exchange. Our proposed protocol dispenses with the external negotiation facility while sticking to the same 4 message exchange. We also implement a smart card application that can generate the messages for the proposed protocol within 1 second and examine its feasibility.
