A Lightweight RFID Authentication Protocol with confidentiality and Anonymity

RFID is an important technology that can be used to create the ubiquitous society. An RFID system uses open wireless radio to communicate and this leads to pose a serious threat to its privacy and security. The current popular RFID tags are some low-cost passive tags. They usually have very limited computing and memory resources and this makes it difficult to protect their security and privacy. Lightweight authentication protocols are considered as an effective approach. Many typical authentication protocols usually use Hash functions so that they require more computing and memory resources. Based on CRC function, we propose a lightweight RFID authentication protocol, which needs less computing and memory resources than Hash functions. This protocol exploits an on-chip CRC function and a pseudorandom number generator to ensure the anonymity and freshness of communications. It provides forward security and prevents information leakage, location tracing, eavesdropping, replay attack, spoofing, and DOS-attack effectively. It is very suitable to some low-cost RFID systems.
