基于Hash函数的RFID双向认证协议

Hash-based RFID Mutual Authentication Protocol

随着物联网技术的发展,射频识别技术被应用在多种领域。针对射频识别系统存在用户隐私泄露、认证耗时等问题,提出了一种轻量级基于Hash函数的RFID双向认证协议,实现了阅读器和标签,阅读器和数据库之间的双向认证。该协议利用Hash函数的单向性和秘钥动态生成的方法,克服了已有协议的不足。最后通过BAN逻辑分析方法形式化证明改进协议的安全性。

With the development of Internet of Things technology, radio frequency identification technology is applied to variousfields. Aiming at the problems of leakage of user privacy and time-consuming authentication in radio frequency identification sys-tems, a lightweight mutual authentication protocol for RFID based on Hash function is proposed, which realizes mutual authentica-tion between reader and tag, reader and database. The protocol uses the one-way nature of Hash functions and the dynamic genera-tion of secret keys to overcome the shortcomings of existing protocols. Lastly, the security of the protocol is improved by formal anal-ysis of BAN logic.
