摘要
针对射频识别(RFID)认证协议安全性较差的问题,设计一个基于动态ID带搜索密钥的RFID认证协议。标签利用单向hash函数的部分输出更新搜索密钥和ID。分析表明,该协议能够有效地实现标签与阅读器之间的相互认证,同时能够抵抗包含前向安全、后向安全、位置跟踪在内的多种攻击,而且硬件需求不高,适合低成本标签使用。
Aiming at the security problem of Radio Frequency Identification authentication protocol, proposes an efficient security protocol for low- cost RFID system based on dynamic ID with a search-key. Tag use of part of the output of the one-way function update the search key and ID. From the result, it can be seen that this protocol can provide authentication between tag and reader, moreover, can resist attacks contain forward traceability, backward traceability, and location tracking. From the implementation point, it just uses a one-way function, which reduces the computing complexity and makes it fitting for low-cost tags applications.
