Research On Lightweight And Secure RFID Authentication Protocols

With the rapid development of Internet of things and the popularization of 5G communication technology,the security of the resource constrained Internet of things devices based on radio frequency identification(RFID)technology has been widely concerned.It is vulnerable to various threats in the process of wireless communication in RFID system,such as denial of service,deception attack and desynchronization attack,so the confidentiality and integrity of data cannot be guaranteed.To meet the security requirements of RFID system,researchers have put forward RFID authentication protocols in recent years.However,some existing protocols are based on traditional encryption algorithms and they cannot meet the lightweight authentication requirement of the resource constrained RFID tag.These protocols are difficult to be directly applied.Some meet the lightweight authentication requirement,but they are vulnerable to security risks that cannot be ignored in the process of wireless communication.And they cause information leakage or illegal access.Some achieve the lightweight mutual authentication,but they ignore the risks of communication between server and reader.These protocols cannot achieve the multi-party authentication among tag,reader and server.Therefore,in view of the above defects in the existing RFID authentication protocols,this thesis proposes two lightweight and secure RFID authentication protocols.The main contributions of this thesis are summarized as follows:(1)We propose a lightweight RFID mutual authentication protocol based on ultralightweight mutual authentication protocol(UMAP)family.We analyze authentication process and performance of protocols in the UMAP protocol family and reveal that strong authentication and strong integrity protocol(SASI)and pseudo-kasami code based mutual authentication protocol(KMAP)have some flaws like vulnerability to common attacks.And they are inefficient.To eliminate these flaws,we design a new authentication model based on blockchain and present a lightweight secure mutual authentication protocol based on UMAP protocol family.The lightweight feature of XOR operation and Hash and uniqueness of consensus ledger of blockchain are used to ensure the confidentiality and integrity.The new protocol can resist common attacks.We utilize several security analysis methods to fully demonstrate the security and correctness of the proposed protocol.Performance comparison shows that the proposed protocol is superior to similar protocols in security and efficiency.(2)We propose a lightweight RFID multi-party authentication protocol based on Hopper and Blum(HB)protocol family.We analyze authentication process and performance of protocols in the HB protocol family and reveal that HB protocol,HB+ protocol and other protocols have some flaws like vulnerability to common attacks and failure to meet multi-party authentication requirement.To eliminate these flaws,we design a multi-party authentication model and present a lightweight secure multi-party authentication protocol based on HB protocol family.Due to the difficulty in solving mathematical problems,such as the learning parity with noise(LPN)problem,the new protocol can resist common attacks and solve the potential problems of communication between RFID reader and server.The new protocol achieves the lightweight multi-party authentication.We utilize several security analysis methods to fully demonstrate the security and correctness of the proposed protocol.Performance comparison shows that the proposed protocol is superior to similar protocols in security.This thesis provides a new idea for the research on lightweight and secure RFID authentication protocols...
