A secure E-tendering system
Shahriyar Mohammadi, Hediy Jahanshahi · 2009
Today E-tendering is increasingly being adopted through the world. An electronic environment presents obvious opportunities for collusion between principal and certain tenderers, fraud by tenderers and attempt of intruders to illegally access the system. In this paper, security requirements of an e-tendering system are described. Then the existing architecture of popular-tendering system are introduced. Then a new architecture for a highly secure E-tendering system is proposed. The new architecture uses encrypted iris pattern as biometric attribute for authentication of tenderers participating in a tender. The proposed architecture uses Shamir threshold crypto system for securing the e-tender box and imposes Bell-LaPadula security model on the access rights of parties involved in the e-tendering system.
