A robust e-commerce service: Light-weight secure mail-order mechanism

Mail order systems offer a convenient purchase service, in which buyers need not visit the store physically and instead choose what they want via a table of contents. Without a third party to play the roles of verifier and recorder, however, buyers face a potential problem of being cheated by a malicious seller. Thus, we aim to develop a mail order system over the Internet that can guarantee user anonymity and secrecy during the transaction process. The low computation of the mutual authentication between the parties involved contributes to the practicality of this new system, while the correctness of this process can be confirmed by the BAN logic model.

► We develop a new mail order system over the Internet. ► The system can guarantee user anonymity and withstand common attacks. ► We examine the correctness of mutual authentication according to the BAN logic model. ► We conduct experiments to show the performance.
