基于Grain-v1的RFID安全认证协议

随着RFID技术的不断发展,RFID的安全问题得到了更多的关注。流密码算法相对其他加密体制,具有简洁、有效、适用于硬件实现等特点。文中从流密码角度,选取了一种资源开销相对较少、硬件实现比较方便的流密码算法-Grainv1,并结合现有的RFID安全认证协议,提出部分改进和优化,使协议本身除了基本的抗攻击性以外更加简洁、有效。同时,通过软件平台的仿真了解数据在协议认证过程中的变化情况和运行效率。

RFID Security Authentication Protocol based on Grain-v1

With the development of RFID technology, security problems in RFID attract more and more attention. Compared with other encrypted systems, stream cipher is simpler in form, easier in hardware implementation and more efficient. And Grain vl, as a stream cipher with less resource using and easier implementation, is selected, and with regard to the existing security authentication protocol, some optimization and improvement by applying stream cipher are proposed, thus making the protocol even simpler and more efficient in communication in addition to its resistance to attack. Simulation in software layer is done to trace the change efficiency in the authentication process of the authentication protocol.
