Delay Model for Flooding of Service Prevention in E-Commerce System

Today´s commercial security server systems which provide secrecy, integrity and availability is still be vulnerable to denial-of-service attacks. Authentication systems which use public key cryptography and process RSA encryption are relatively slow. This has become a major security threat specifically in flooding of service attacks caused by authentication requests. The service flooding attacks render the server incapable of providing its service to legitimate users. In this paper, we propose a delay protocol which applies to the authentication model. Our gradually strengthening authentication model improves the availability and continuity of services and prevents denial of service attacks. We implemented a flooding of service tolerance system to verify the efficiency of our model. This system will greatly increase the reliability.
