基于M序列的轻量级RFID认证协议

A Light-Weight RFID Authentication Protocol Based on M-Sequence

尽管RFID的应用领域越来越广泛,但其安全和隐私保护问题没有得到很好的解决.在以前的大多数RFID认证协议中,服务器的搜索量和标签的个数有关,基于M序列提出了一种轻量级RFID认证协议.在提出的协议中,服务器的搜索量和标签个数无关.基于M序列的伪随机性和利用Hash函数的单向性,该协议具有抗重放、抗分析、防伪造、防跟踪等安全属性.

Although the RFID technology is more and more widely used, security and privacy problem of RFID has not been completely solved. In most RFID authentication protocols, the search volume of the server depends on the number of tags. A light-weight RFID protocol is proposed based on M-sequence. In the proposed protocol, the search volume of the server does not depend on the number of tags. Based on the pseudo-randomness of M-sequeuce and the unidirectionality of hash function,the proposed protocol can resist replay attack,statistical analysis,spoofing attack,privacy track and so on.
