摘要: 基于RFID系统工作原理和低成本标签存储计算能力有限的特性,提出一种新的RFID标签所有权转换协议.协议通信过程采用轻量型运算,标签以假名经伪随机加密函数处理后在无线信道传输,采用共享密钥恢复机制进行标签与所有者之间的认证、授权,保证了协议的健壮性;密钥由通信双方协商动态更新,提高了标签在所有权转换过程中信息数据的安全性.与其他协议比较分析结果表明,该协议低复杂度的算法可以抵抗多类攻击,且具有较低的通信量和较高的计算效率.Abstract: Based on the mechanism of RFID system and limitation of low-cost tags which storage capacity and computing ability,a new RFID tag ownership transfer protocol was presented. In communication process of protocol,lightweight operations were adopted,tag anonym was transmitted in wireless channel which was processed by Pseudo-random Encryption Function. Shared-key recovery mechanism was used to excute authentication and authorization between tags and owners,which could ensure the robusthess of the protocol. At the same time,the shared-key dynamically negotiated and updated by both communication sides. It improved the security of information data in the process of ownership transfer. The analysis results compared with other protocols showed that the protocol could resist various attacks by low-complexity algorithms,and had lower traffic and higher computation efficiency.
