An Improved and High-efficiency RFID Encryption Security Protocol

Radio Frequency Identification(RFID) is widely used in wireless signal system. However, with the development of RFID,security issues based on its non-contact type are paid more attention. Pointing at the privacy problems, this paper proposes an improved RFID encryption security protocol with high-efficiency, which combines Hash function, bin-search algorithm and Cyclic Redundancy Check(CRC)test together. It realizes the fast research progress, and avoids the interference of tampering label to the background information system.Security analysis and performance evaluation result show that this protocol has comprehensive advantages in security property, antiattack capability and identification rate compared with Hash-Lock protocol, Hash-Chain protocol and SPA protocol.
