一种低成本的标签组存在证明协议

A Low Cost Proof Protocol for the Label Group Existence

现有大多数协议仅能证明单标签存在不足,对此给出一种适用于检验是否同时存在多标签的证明协议。所设计协议适用于低成本无源标签中。采用线性函数对传送信息进行加密,在线性函数构造过程中巧妙运用加密信息汉明权值作为参数,从而减少参数引入,降低计算量及存储空间。对所设计协议进行理论分析和仿真,表明所设计协议不仅能够证明多标签同时存在,且在计算量及安全角度优于其他经典协议。

In order to solve the problem that most of the existing protocols can only prove the existence of single label,this paper presents a proof protocol which is suitable for checking the existence of multiple tags simultaneously.In order to be suitable for low-cost passive tags,a linear function is used to encrypt the transmitted information;in the process of constructing linear function,the encrypted information is used skillfully to obtain the parameters of Hamming weight,so as to reduce the introduction of parameters,reduce the amount of calculation and storage space.The theoretical and simulation results show that the proposed protocol can not only prove the existence of multiple tags at the same time,but also outperform other classical protocols in terms of computation and security.
