摘　　要：当前智能仪器设备标签的远程识别,虽打破了以往人工记录的传统模式,但基于WLAN技术的远程识别,无法保证传输过程的安全保密性,为此提出基于WAPI技术的智能仪器设备标签远程识别研究。首先,在分析智能仪器设备标签远程识别频率的基础上,确定标签芯片的三种阻抗变化;其次,在WAPI技术下,根据对等保密访问的特性,协商远程识别的密钥,进而通过绑定智能仪器设备标签数字证书,实现高效远程识别。根据对比实验的结果可知,在识别距离为3 m,以及识别设备数量为490的前提下,基于WAPI技术的智能仪器设备标签远程识别方法,在保证识别成功率的基础上,保障了识别过程的安全性,其识别安全率高达96.1%。At present,the remote identification of intelligent instrument labels breaks the traditional mode of manual recording,but the remote identification based on WLAN technology can not guarantee the security of the transmission process.the research of remote identification of intelligent instrument labels is proposed based on WAPI technology.Firstly,based on the analysis of the remote identification frequency of the tag,three impedance changes of the tag chip are determined;Secondly,in WAPI technology,according to the characteristics of peer-to-peer secret access,the key of remote identification is negotiated,and then the efficient remote recognition can be realized by binding the digital certificate of the label of intelligent instrument and equipment.According to the results of comparative experiments,under the premise that the recognition distance is 3 M and the number of recognition devices is 490,the remote recognition method of intelligent instrument tag based on WAPI technology ensures the security of the recognition process on the basis of ensuring the recognition success rate,and the recognition security rate is as high as 96.1%.
