摘要
嵌有RFID标签的物品归属权在应用中会经常发生转移,相对应的所有权亦必须发生转移。为保障所有权在转移过程中隐私的安全性,提出一种基于按位操作的标签所有权转移协议BBO。采用交叉合成位运算对信息进行加密,并引入标志位;根据标准位的值知晓所有权当前归属者。安全性分析表明,该协议满足标签所有权转移的安全需求;性能分析表明,该协议能够有效减少标签端的计算量。
The ownership of goods embedded with RFID tags often transfers in applications,and the corresponding ownership of goods must also be transferred.In order to protect the privacy of ownership in the process of transfer,this paper proposed a label ownership transfer protocol BBO based on bitwise operation.The protocol encrypted the information by cross-composing bit operation and introduced flag bit.According to the value of flag,we knew the current owner of the ownership.The security analysis shows that the protocol satisfies the security requirement of tag ownership transfer,and the performance analysis shows that the protocol can effectively reduce the computation of tag end.
