Abstract
Aimed at the security problems of RFID system in the Internet of things, this paper proposed a kind of light-weight RFID security protocol based on the algorithm of Present. The algorithm of Present belongs to the light-weight grouping encryption algorithm, and its logic gates are simple in structure, and it has a low computational complexity, which meet the requirements of lightweight security protocols. The database and tag make the mutual authentication through the encrypted information by the algorithm of Present and the two-way random number as the protocol freshness. This paper used the security analysis and BAN logic to prove the security of the protocol. Compared with other light-weight protocols according to the result of security analysis and BAN logic, this protocol ensures the security of RFID system and does not occupy too many hardware resources, and meets the requirements of low-cost RFID communication security.
