融合安全与反碰撞的RFID处理机制

RFID Processing Mechanism Integrating Security and Anti-collision

现有的RFID研究将RFID安全和RFID反碰撞看作2个不同的环节分别孤立地解决。针对该不足,将两者作为一个整体进行研究,采用的方法是将轻量级的随机密钥双向认证和动态时隙ALOHA协议进行融合。给出其处理机制流程,并和其他方法的性能进行对比分析。研究表明,该机制在保持对标签快速识别的同时,可抵抗包括重传、跟踪、阻断和篡改等多种攻击手段,具有较高的安全性和实用性。

Integrating RFID security and RFID anti-collision are research hotspots of RFID technology in the Internet of things.Its shortcoming is them being resolved as two different parts.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 and performance comparison 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.
