A High Security RFID System Authentication Protocol Design Base on Cloud Computer

With the rapid development and vide application of RFID technology, the security and privacy protection of RFID system are increasing attention of people. To solve security and privacy protection problems of RFID system, propose a new authentication protocol. It uses elliptic curve cryptography and advanced encryption standard to encrypt the authentication process. Introduce timestamp as the tag query mark. Introduce gather idea to manage the tags and readers in the database. With the analysis of the common attacks of RFID system, prove the authentication protocol can resist location tracking, replay attack, spoofing attack and other means of attack. It also achieves mutual authentication, key update, forward security and other properties. This authentication protocol has certain application areas. It can meet the high security and privacy protection requirement of bank, government, military and other departments.
