摘要:

针对日益突出的RFID系统安全隐私问题,提出了一个基于混沌序列的RFID双向认证协议。利用混沌对初始值的敏感性生成混沌序列,对密钥进行加密。该协议引入标签密钥动态更新机制,并设计了自同步解决方案,实现了对标签的二次认证。采用BAN逻辑对其安全性进行证明,并与已有的协议进行安全性分析和性能比较。其分析结果表明,该协议降低了标签成本,减少了标签和后端数据库的计算量,提高了后端数据库的检索效率。不仅有效地解决了RFID系统的隐私保护及安全问题,同时也提高了RFID协议认证的执行效率,更适合低成本的RF1D系统。

Abstract:

Since the security privacy issues of RFID systems are increasingly prominent, we propose a RFID mutualauthentication protocol based on chaotic sequence encryption to tackle those problems. Chaotic sequence can be generated to encrypt the keys by making full use of the sensitivity of chaos to the initial value. An update mechanism of the dynamic tag keys is introduced and a selfsynchronized scheme is designed, which achieves a second verification for the tags. The security of the protocol is verified by the BAN logic, and it is compared with the existing schemes in terms of security and performance. The results show that the proposed protocol can greatly decrease the cost of tags, reduce the amount of computation of tags and the backend database, and enhance the search efficiency of the backend database. It can not only effectively solve the privacy and security issues of the RFID system, but also improve the efficiency of the RFID system, thus being more suitable for the low cost RFID system.
