摘要
针对目前的RFID协议采用的认证和密码体制存在安全性问题及性能相对低下,提出一种基于快速NTRU(Number Theory Research Unit)密码体制的RFID三方相互认证协议。该协议首先将NTRU密码体制与异或等运算相结合从而实现服务器、阅读器及标签之间的相互认证,然后分析它的安全性及可行性,最后与其他相关认证协议进行比较分析。结果表明该协议能够为RFID系统在相互认证方面提供更高安全性及良好的性能表现,从而适应于低成本及效率较高的RFID标签。
Due to that the authentication and cryptosystem used by current RFID protocol have security problems and relatively low performance,we propose a fast NTRU cryptosystem-based RFID tripartite mutual authentication protocol. This protocol combines NTRU cryptosystem with exclusive OR operation so that achieves the mutual authentication between the server,the reader and the tag. We analyse its security and feasibility,and comparatively analyse it with other related authentication protocols as well. Result demonstrates that the protocol can provide higher security and good performance for RFID system in mutual authentication,so that it is adapted to the RFID tags with low cost and high efficiency.
