摘　　要：针对现有的RFID安全协议计算成本较高及无法抵御完全的主流RFID攻击,提出一种基于秘密身份与单向hash函数的轻量级安全协议。第一阶段,标签向数据库注册,数据库为标签分配一个一次性的秘密身份与一个唯一的秘钥;第二阶段,基于一次性秘密身份与单向hash函数进行标签-阅读器-数据库之间的双向认证,实现了对各种攻击的检测与抵御能力。最终,将本协议与近期性能较好的双向认证协议进行比较。结果表明,本协议与其他协议的计算成本、内存需求接近,且具有完全的攻击抵御能力。The computational cost of the existing RFID security protocols is high or the existing protocols can＇t defense the all kinds of the popular RF]D attacks, a secret identity and one-way hash function based highlight security protocol. In the first phase, tag registers to dataset, dataset assigns a one-time secret identity and one unique secret key to the tag; in the second phase, the mutual authentication of tag-reader-dataset is processed by one-time secret identity and one-way hash function, and the detection and defense power of all kinds of attacks is realized. At last, the proposed protocol is compared with several recent mutual authentication protocols, the results show that, the proposed protocol has similar computational cost and memory cost with the other methods, but the proposed protocol can defense complete attacks.
