Analysis and Improvements of a Secure E-Tender Submission Protocol

The Du-Boyd-Foo Extender protocol is the first protocol to address the issue of security in e-tendering. However, it dose not cater for re-submission because each tender is allowed to submit only once. In this paper, we show that the Du-Boyd-Foo protocol is vulnerable to a realistic man-in-the-middle attack, revise the protocol to make it immune to such attack, and extend it to also apply to re-submissions. In doing so, we enhance the protection against both man-in-the-middle and cheating-tenderer attacks that are possible in re-submissions. This work extends the usefulness of the Du-Boyd-Foo protocol by making it more secure and more general.
