动态双向Hash认证的RFID安全协议

射频识别(RFID)系统利用无线射频技术以非接触的形式,在开放的环境下通过电磁波进行对象识别。但由于RFID系统的特殊性和实际要求的一些局限性,给射频识别带来了很多安全问题。如何设计出适合于RFID系统的高效、安全的认证协议是RFID系统能够进一步广泛应用的关键。本文通过分析现有的典型的RFID安全协议,在了解它们的特点和缺陷的基础上,提出了一种RFID动态协议。通过相关协议的比较表明,该协议是一种安全、高效、隐私性好的认证协议。

RFID Cryptographic Protocol Based on Dynamic Mutual Hash Authentication

Radio Frequency Identification （RFID） system using the radio frequency technology in the form of non-contact and under open environment by electromagnetic wave is used to identify the object. But due to the particularity of the RFID system and actual require ments of some of these limitations, many security problems come to RFID system. How to design an efficient and secure protocol suit able for the RFID system is the key problem for the RFID systems＇ popularization. Based on the analysis of the existing typical RFID se-curity protocol, this paper proposes a RFID dynamic protocol. By the comparison of the relevant agreements, this is a safe, efficient, good privacy certification protocol.
