A Confidential Passive UHF Reader with Cryptographic Technique

In this paper, a passive UHF reader design with cryptographic technique SM2 is presented. By designing board compatibility of security module, RFID control module, RF module, communications interface, the passive UHF reader can both operate at common mode and security mode. This design constructs a suitable candidate for reliability, integrity, security of information transmission of RFID application in special field of internet of things.
