一种物联网感知数据安全传输方案

A Secure Transmission Scheme of Sensing Data in Internet of Things

无线传感器网络(WSN)能够利用传感器节点快速准确获取物理世界的信息从而作为物联网的感知层在监控领域得到了广泛的应用,无线传感器网络通常部署在公共或其他不可信甚至敌对的环境中,这会引发许多安全问题。虽然安全性在其他网络中也是存在的,但由于无线传感器节点能力和资源有限,使得传统的安全机制不能直接应用到无线传感网中。提出了一种基于LEAP+的轻量级密码算法,并使用TOSSIM平台进行了仿真,结果表明该轻量级算法在有效保护数据的安全传输的同时不会导致节点的能耗加大。

Wireless Sensor Network(WSN)could use sensor nodes to quickly and accurately obtain the information of the physical world,which has been widely used in the field of monitoring as the sensing layer of the Internet of Things.WSN is usually deployed in public or other untrusted or even hostile environment,which will cause many security problems.Although security also exists in other networks,due to the limited capacity and resources of wireless sensor nodes,the traditional security mechanism can not be directly applied to wireless sensor networks.A lightweight cryptographic algorithm based on leap+is proposed,and TOSSIM platform is used for simulation.The results show that the lightweight algorithm can effectively protect the transmission of sensing data without increasing the energy consumption of nodes.
