An investigation and design of certain rfid security protocols For cloud based supply chain management applications

Abstract

In Supply Chain Management (SCM) system, products are moved from supplier to customer. It integrates and coordinates the flow of material and information from supplier to manufacturer, wholesaler, retailer and to consumer. Effective supply chain management system ensures the availability of product when needed. In this regard, Radio-Frequency IDentification (RFID) technology in the supply chain ensures that the right goods are available in the right place. RFID makes the supply chain considerably more precise and improves the efficiency and reliability of the entire chain. Business organizations are trying to overcome the supply chain bottlenecks by integrating the best technologies possible. In recent years, there has been an influx of cloud based SCM solutions hitting the market. Security is seen as a big challenge for cloud based SCM. This research work focuses on authentication issues in the various processes of cloud based SCM applications in which objects are tagged with an active RFID tag. In this work, the existing RFID based security protocols are investigated and analyzed against known security vulnerabilities and also their performance with respect to the active RFID tag is evaluated. It is observed that many of the existing RFID protocols are computationally intensive. This motivated us to provide secure RFID authentication protocols with less computation in the RFID tag and without any trusted third party for cloud based SCM. newline
