A Secure Revocable Ring Signature based Auction System for E-commerce Application

The Electronic bidding system has been increased among recent years. Because many people's use to buy as well sell in internet with the use of auction websites available well sell in internet with the use of auction websites available in these type of auction systems. So we have to identify the frauds and also we have to secure the auction bidding scheme. In this paper we are introducing a secure type of auction bidding using the group signature technique (6). The group signature technique is an old technique but we are introducing the scheme using the RSA Algorithm. We named the Group signature technique as the Revocable Ring signature Technique (11). This technique the user can freely join any group available in the auction system. But earlier they can't change their group. But in this they can change their groups from one to another and also they can form their own group .each group may place their personal input. And this is known as the curve type cryptography. Initially in the Existing system they used the Elliptical curve Cryptographic method. Here we establish the RSA Algorithm in it. By using this method Effective auctioning is done. The Security Level has been reasonably increased in this new auction system. This system will provide a secure auction. Efficiency and the Performance level is also being improved in this System.
