A lightweight and efficient RFID authentication protocol based on synchronization code

While RFID technology is widely used, its security is facing serious challenges. Under the premise of ensuring safety performance, how to save system cost and improve efficiency has become a research focus. We propose a lightweight and efficient RFID authentication protocol base on synchronization code after analyzing the defects of various protocols and referring to the synchronization digital principle of code hopping encoder. This protocol guarantees the security of the system by using synchronous number and bidirectional authentication mechanism, and analyzes the threats to ensure the safety of the protocol. Comparing with other protocols, the proposed protocol is of low cost and efficient. Finally, the BAN logic protocol is adopted for a formal analysis, which theoretically proves the feasibility of the proposed protocol.
