Abstract

In this paper the authors present a practical approach of fairness in E-procurement. A generalized model of E-procurement is also presented here, which includes both E-contracting and E-trading. The model also proposes the generalized methodologies to develop E-procurement protocols that ensure fairness in true sense without using an additional trusted third party. They conclude this paper by indicating the area of applicability for their model.

2. Previous Work

In this section we discuss briefly some related work in providing fair-exchange in E-commerce. In previous works, trusted third party (TTP) is used in most of the fair exchange protocols either in offline mode or in online mode. By using the third party in off-line mode, the optimistic fair exchange protocols have a considerable contribution in the field of fair exchanges in E-commerce. There are some GSR protocols for fair exchange in which the participants increase the probability of fair exchange gradually over several rounds of message exchanges.
