Design and analysis of security protocol for RFID without back-end database

RFID security protocol is one of the most important ways to solve security problems of RFID system and it is the focus of current research. This article summarized and classified the common security protocols, then proposed a new mutual authentication protocol without the back-end database which aimed at the actual need of military applications and proved the correctness of the new protocol by GNY logic. Safety analysis shows that the new protocol can effectively protect privacy, prevent tracking and avoid synchronization attack and such common problems. The protocol has not only high security, but also the obvious advantage of flexibility.
