Rfid Authentication Protocol for security and privacy Maintenance in Cloud Based Employee Management System

Cloud based RFID authentication is becoming a large area of interest among researchers and engineers these days. However, there is not much attention given to the RFID authentication concern. Most of the work done on this issue till now has its focus on RFID functionality without considering security and privacy. Classical RFID authentication schemes do not meet the security and privacy requirements of cloud based RFID. Main features available in traditional backend-server-based RFID authentication are secure backend channels and purely trustworthy database, which are not available when moved to cloud based scenarios. Here the concept is implemented on employee management system. Many organizations now days wants have a high-tech employee management system using which a salary, attendance and location of a particular employee within an organization can be easily find out. An organization invests a large amount of money for developing and maintaining its own software and system. As compared to traditional model, newly adapted cloud based IT model is more cost effective but they are having the problems of insecure database and disclosing the privacy of tags and readers. So, there is a RFID authentication protocol is developed and VPN agency is suggested to build secure backend channels. It will secure the database using hashing technique and preserves the privacy of tags and readers by providing backend communication over secure channels. Proposed scheme has the advantages like deployment cost saving, pervasiveness of authentication, database security and mobile reader holders privacy.
