Research On Security Authentication Protocol Of RFID Perception And Recognition System Based On Improved ECC

With the development and application of the Internet of Things,RFID(Radio Frequency Identification)perception and recognition technology has also developed rapidly.In RFID system,reader and transponder use wireless signals for data communication.During the communication process,the attacks on RFID have seriously affected the security and privacy of users.From the existing literature,RFID system security protection methods nowadays can mainly be divided into physical methods and cryptography methods.The advantage of the physical methods is that the operation is simple.The disadvantages are the high cost and the limitation of normal communication.The alternative method is the security authentication method,such as using simple logical operation,Hash function and so on.But such security authentication method is of low security,and can't meet the demand of high security requirements of RFID system.The cryptography methods mainly include: symmetric encryption algorithm and asymmetric encryption algorithm.Both algorithms are of high security,but the computational complexity and storage capacity are relatively large.In order to improve the prevention ability of the RFID system against various attacks and meet the requirements of system security,the security authentication of the RFID system is studied,and the improved ECC(Elliptic Curves Cryptography)algorithm is used to solve the problem.This paper mainly addresses the security and privacy issues of RFID perception and recognition system.By studying the security authentication protocol of RFID,the elliptic curve cryptography ECC requires less storage consumption,shorter transmission information and higher efficiency among high security authentication encryption methods.Therefore,this paper chooses to improve the ECC ellipse encryption method with high security,to get a new security authentication protocol.In this paper,the protocol combines random numbers and key arrays that have variable array size on the basis ofECC,which improves the scalability of the protocol usage scenario.After each authentication,the key arrays are dynamically updated to make the authentication protocol more secure and to defend against more attacks,thus solving the security and privacy issues in the RFID perception and recognition system.The authentication protocol is compared with several authentication protocols based on ECC curve cryptography in calculation,transmission,storage consumption and security.The result is that the authentication protocol has better computational efficiency,transmission overhead and security.This paper first introduces the RFID system and the existing security privacy issues.Then it studies the security authentication protocol of RFID,and describes and analyzes the security authentication protocol and the anti-attack capability of protocol.The feasibility of the protocol in this paper is obtained an example and an experiment.Finally,the performance of this protocol is compared with several protocols.
