RFID security and RFID anti-collision are research hotspots of RFID technology in the internet of things, most of the existing studies took them as separated parts and researched them individually. This paper attempts to deal with them as a whole, with a strategy integrating lightweight random key double-authentication and dynamic slot-ALOHA protocol. The processing mechanism, performance comparison and algorithm realization are given in this paper. The new mechanism not only maintains the advantage of rapid tag identification, but also has the ability to resist re-transmission attack, tracking-attack, blocking-attack, tampering-attack and so on. It has a high safety and practicality.
