基于随机Hash-Chain的RFID安全协议研究

Research on Random Hash-Chain Cryptographic Protocol for RFID

无线射频识别(RFID)作为一种新型的自动识别技术正逐渐得到广泛应用,但RFID系统的特点和RFID设备的局限性带来了很多安全隐患问题。针对这些问题,讨论并阐明RFID系统组成和安全隐患,分析了几种现有的典型的RFID安全协议的特点和缺陷,最后提出了一种基于随机Hash-Chain的RFID安全协议。

Radio Frequency Identification（RFID） as a new automated identification technology has become popular in many applications. But the features of the RFID systems and the constraints of RFID devices bring about various privacy problems. To address these issues, the structure and privacy problems of RFID systems were discussed and clarified in this paper, and the features and issues pertinent to several current typical RFID cryptographie protocols were analyzed Finally, a new cryptographic protocol for RFID based on random Hash-Chain was proposed.
