摘要: 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。

Abstract: 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.
