Abstract: In the business world, exchange of receipts of business transactions is a common practice. These receipts serve as evidences that the transactions did take place in case of future repudiations and disputes. Likewise, it is critical in e-commerce applications to have a third party security service, which generates, distributes, validates, and maintains information and evidence of an electronic transaction. Quite a number of non-repudiation protocols have been proposed and evaluated based on some established evaluation criteria. However, in the context of collaborative e-commerce, there are additional evaluation criteria to be considered: e.g., the recipient role in the protocol execution, the degree of trust on a third party, and the dependency on the existence of a third-party for dispute settlement. In this paper, we identify a number of security requirements in collaborative e-commerce, and propose a new non-repudiation message transfer protocol, which makes use of the techniques of message digest, message encryption, double-encrypted key, and dual signatures. The protocol can satisfy the additional criteria better than the existing protocols. The implementation of the protocol in the web service platform is also presented.

Keywords: collaborative e-commerce; electronic commerce; security protocol; digital evidence; digital signature; non-repudiation; message transfer protocols; message digest; message encryption; double-encrypted key; dual signatures; web services; business process integration.
