摘　　要：针对RFID标签在认证授权及所有权转换过程中存在的安全隐私问题,结合类编程思想和重载原理,提出一种基于动态重载的RFID标签所有权转换协议.其要点为:在PUF部件的基础上改进伪随机序列生成器的迭代机制,以芯片产生的自编译扩展因子增强输出的随机性;为通信双方构建轻量级候选函数集,利用面向对象编程中的"重载"原理实现所有权转换过程中算法的动态执行.协议安全性及计算开销分析对比结果表明,新协议在认证授权的基础上提供标签所有权的安全转移,与同类协议相比具有较高的安全性和较低的计算开销.Aiming at security and privacy issues existing in the process of authentication and authorization of RFID tags ownership transfer,combining with the principles of Class-Programming and overload,a RFID tag ownership transfer protocol based on dynamic overload was presented. It improved iterative mechanism of pseudo-random sequence generator on the basis of an PUF component,utilized self-compiling extension factor generated by chips to enhance randomness of output,constructed lightweight set of candidate functions for both communication sides so as to achieve dynamic execution of algorithms in ownership transfer process which via the overload principle in Object-Oriented programming. The security and computing cost of protocol analysis results showed that the new protocol provided tag with secure ownership transfer on the basis of authentication efficiency and authorization,and it had higher security and lower computation cost compared with similar protocols.
