and transparent manner, and also provide confidence
to participants and creates a high degree of trust in the
process.
The goal of any electronic system trying to
achieve what has been traditionally carried out in the
brick-and-motor world should be, not only to repli-
cate the requirements of the traditional system but, to
improve the system to provide better services. We
have proposed an e-tendering system that achieves
such a goal. E-tendering systems previously pro-
posed do not adequately address the need for fair-
ness. Our proposal provides a publicly verifiable fair
e-tendering system that not only meets all the secu-
rity requirement of the traditional tendering system,
but offers new services such as anonymity and, ten-
dering hiding and binding.
