Proposed system structure can be used in any World-Wide Web technology to make possible implementation of a secure electronic tender processing system. This System offers possibilities considering both cost-effectiveness and security. Providing mutual authentication [11,12] is the correct way to make possible secure communication and transmission of data among parties with reliability, confidentiality & security in WAN, MAN, LAN etc technologies used in Electronic Tender Processing & this can be achieved by using Kerberos as an Authentication services. In this paper the system structure and communication protocol of a system utilizing these possibilities are proposed, that should be profitable when designing a final implementation.
