摘要
针对海量标签应用导致RFID系统成本提高的缺点,本文分析现有RFID安全协议的特点及局限性,提出重点关注功能强大的读写器,并提出一种新的基于读写器和双重ID验证的RFID安全协议。读写器对标签的ID(伪ID)进行第一次验证,然后该伪ID与替换表配合,形成一个新的真实ID,读写器进行第二次验证。整个通信过程采用Hash加密和随机数发生器来提高系统安全性。分析结果表明,该协议可以明显降低RFID系统的成本,防止网络攻击,适合于大规模使用标签的RFID系统中。
Aiming at the high cost of RFID system because of the massive tags application, the paper analyzes the characteristics and limitations of the existing RFID security protocol, puts focus on the strong function of the reader, and proposes a new RFID security protocol based on reader and double ID verification. The reader is first verified on the tag ID（fake ID）, then the fake ID is joined with the replace table and forms the real ID, and finally the reader is second verified. In the whole communication, Hash encryption and random number generator are adapted to improve the security of the system. Analysis results show that the proposed protocol can significantly reduce the cost of RFID system, prevent network attacks, and be suitable for RFID system in large-scale use tags.
