Research And Design Of RFID Security Authentication Protocol In Internet Of Vehicles

Radio frequency identification technology is one of the core technologies of the Internet of Vehicles.The license plate with RFID tags will be the future development trend.However,due to the openness of the wireless channel between the tag and the reader in the RFID system of the Internet of Vehicles,the communication content is easily eavesdropped and tampered by attackers.The security and privacy issues are becoming the key to restrict the application of RFID technology.In response to the above problems,a variety of RFID authentication protocols have been proposed,but most of the protocols cannot fully adapt to the practical and security requirements of the IoV RFID system.Therefore,based on the existing protocols,two new security protocols applicable to the Internet of Vehicles RFID system are proposed,and the protocol is analyzed for security,logic and FPGA.The main work of this thesis is as follows:(1)Aiming at the problem that the existing security protocols cannot solve the DoS attack in the Internet of Vehicles,Based on the three-round authentication protocol,a security authentication protocol based on the key distribution center is proposed.The label with no legal key is filtered first through the updateable private key stored in the key distribution center,and then authenticated by the background server.While solving the security problems such as counterfeit attacks,replay attacks,and tracking attacks in traditional protocols,it also solves the denial of service attacks in the Internet of Vehicles.Through the BAN logic proof and the comparison of security and performance analysis,it shows that this protocol can provide effective security protection in the Internet of Vehicles,which greatly reduces the computing burden of the background server facing multiple tags.(2)Aiming at the problem of information encryption and decryption and anti-denial in the IoV RFID system,a secure authentication protocol based on elliptic curve cryptography is proposed.Through the public key cryptosystem of the elliptic curve,the information encryption and decryption of the label to the background server is completed,and the signature algorithm is used to prevent the label denial problem,and the two-way authentication between the label and the background server is realized.Through security analysis,it can resist attacks such as counterfeiting,replay,and denial.The protocol achieved high security strength with minimum key length and calculation amount,and can meet the security communication requirements of the IoV RFID system.(3)The FPGA design and simulation of the elliptic curve cryptographic protocol is carried out.The hierarchical structure of the elliptic curve cryptographic protocol is divided into three layers: protocol layer,point operation layer and finite field operation layer.The algorithm in Addition and subtraction,multiplication,square and modular inverse for finite field,point addition,point multiplication and encryption,decryption,signature were studied,and then joint simulations with ISE and ModelSim were completed to prove the achievability of the above protocol in hardware.
