基于无线传感器网络的燃气管道检测系统身份认证技术

Authentication Technology of Gas Pipeline Inspection Based on Wireless Sensor Networks

介绍了基于无线传感器网络的燃气管道检测系统的身份认证技术。该系统通过安装在管道中的节点对由于管道受力变化引起的电压变化进行采样,然后通过无线通信将此信息发送给采集器,再由采集器发送给服务器,从而判断管道是否受损。由于无线通信的开放性,身份认证技术在此系统中得到了充分应用。基于秘密信息和物理安全性的身份认证技术能够对通信双方进行身份鉴别,防止未授权方获得数据。

A gas pipeline inspection system based on wireless sensor networks is introduced in this paper. The voltage changes caused by force change in some nodes in the pipeline shall be sampled and sent through wireless communication to collector, and then the collector shall send it to the server, who will judge if the gas pipeline is impaired. Authentication technology has been fully applied in this system. Authentication technology based on secret information and physical security will ensure the communication being under warrant and avoid unauthorized party getting the information.
