【摘要】：针对移动无线射频识别认证协议面临的身份认证和隐私保护、动态密钥安全更新和去同步化攻击问题,提出一种可动态更新共享密钥的移动RFID双向认证协议.协议基于Hash密码机制,利用随机数同时进行密钥安全更新和身份认证,并采用对分表存储的当前和历史共享密钥进行动态添加和删除的方法,保留最后一次合法认证后的一致共享密钥.安全性能分析与效率分析表明,该协议能够实现动态密钥安全更新和身份认证、能够在遭受去同步化攻击后保证密钥同步,且具有较强的计算和存储性能.通过和同类RFID认证协议比较,协议弥补了同类RFID协议存在的不足,适用于被动式标签数量庞大的RFID系统.
[Abstract]:Aiming at the problems of identity authentication and privacy protection, dynamic key security update and de-synchronization attack faced by mobile radio frequency identification authentication protocol, a mobile RFID bidirectional authentication protocol which can dynamically update shared key is proposed. The protocol is based on Hash cryptosystem, uses random numbers to update and authenticate the key simultaneously, and dynamically adds and deletes the current and historical shared keys stored in the table. Keep the uniform shared key after the last legal authentication. Security performance analysis and efficiency analysis show that the protocol can realize dynamic key security update and identity authentication, and can guarantee key synchronization after the attack of de-synchronization, and has strong computing and storage performance. Compared with the similar RFID authentication protocol, the protocol makes up for the deficiency of the similar RFID protocol and is suitable for the RFID system with a large number of passive tags.
