摘要:

随着射频识别技术的广泛应用,其引发的安全问题和计算开销之间的矛盾愈发突出。为此,研究主流射频识别安全认证协议存在的安全缺陷,分析其计算开销,设计一种安全性高、计算成本低的安全认证协议。通过串空间模型方法对协议进行分析,得出协议可以安全可靠地实现读写器与标签的双向认证。分析结果表明,该协议能够抵抗假冒、窃听、重放、类型缺陷和位置跟踪等攻击,具有较好的前向安全性,且运算开销小,适用于各种低成本的射频识别系统。

Abstract:

With the extensive application of Radio Frequency Identification(RFID),the contradiction between its security and computation is serious.On this background,the security defects and cost of the main RFID secure authentication protocols are analyzed.On this basis,a new authentication protocol is promoted with higher security and lower cost.Its security is verified via the strand space model,which proves that the mutual authentication of reader and tag can be realized safety and reliability.The analysis results show that the protocol is resistible to attacks such as spoofing attack,eavesdrop attack,replay attack,type flaw attack,tracking and so on,and also provides perfect forward secrecy,which has a lower computation,and is suitable for low-cost RFID system.

Key words: Internet of Things(IoT), Radio Frequency Identification(RFID), authentication protocol, strand space model, safety analysis
