RFID Security Using miniDES Algorithm in Deployment of Bike Renting System

摘要

Radio frequency identification (RFID) is a generic term that is used to describe a system that transmits the identity (in the form of a unique serial number) of an entity or person wirelessly, using radio waves. Unlike bar-code technology, RFID technology does not require contact or line of sight for communication. RFID data can be read through the human body, clothing and non-metallic materials. RFID Systems technically consist of RFID Tags, Readers, Communication Protocols and Information Systems. These technical parts enable the collection of data on the tagged object or person. In most of today's RFID Systems the data on the tag is accessible by anyone who is able to operate a RFID reader in such cases how much these RFID tags are protected? The tags accessed data should be only readable to authenticated people. The challenge in providing security for low- cost RFID tags is that they are computationally weak systems, unable to perform even basic symmetric-key cryptographic operations et al "ARI JUELS(2004)" . Security for RFID systems has to start at the base of the technology. Information on the tags has to be stored in a secure way by using a lightweight crypto algorithm. The? processing capabilities of many RFID based embedded systems are easily besieged by the computational demands of security processing, leading to failures in sustaining required data rates or number of connections et al "SRIVATHS RAVI & ANAND RAGHUNATHAN, PAUL KOCHER, SUNIL HATTANGADY" . In this paper, I explore a concept of miniDES symmetric key algorithm is suitable for RFID tag security deploying in the Bike renting system. I consider the type of security obtainable in RFID based devices with a small amount of rewritable memory, but very limited computing capability. My aim is to show that miniDES algorithm is efficient and sufficient to provide the security for the RFID based systems, there is no need for very complex cryptography algorithms which requires high power of computational power. And the automation of bike renting system definitely enhances the performance of the bike renting process
