一种基于Hash的RFID双向认证的安全协议

An improved RFID mutual authentication protocol based on Hash function

对RFID技术所面临的安全问题进行分析,结合当前RFID认证协议的优缺点,提出了一种基于Hash函数的RFID双向认证的协议.协议采用随机数与动态ID结合的双向动态认证,通信认证过程加密.与同类型协议对比分析表明,该协议可以有效抵御非法读取、位置跟踪和重放等安全问题,同时能够满足标签低成本的需求,并且有着更优的执行性能.

Based analysis of the security issues of RFID technology, integrated advantages and disadvantages of the current RFID system authentication protocol, a new mutual authentication RFID protocol based Hash function was proposed. The protocol adopted mutual dynamic authentication with random number and dynamic ID, communication authentication progress in encryption. Compared with the same type of RFID protocol, it shows that the protocol can be effective against unauthorized read - out, location tracking, replay, and can meet the low - cost needs of tags with a better performance.
