Enabling security on low-power nodes in remote wireless sensor networks

访问远程信息已经变得无处不在。传感器部署在各种各样的环境中，包括森林和山区、海洋上空或北极等偏远地区。此外，可在紧急情况下部署现场无线网络。这些网络通常依赖于低成本的节点。为了使数据能够在这些自组织网络上传输，一个标准的通信堆栈被编程到节点上。该堆栈包括安全特性，以避免不受欢迎的用户的入侵和破坏。然而，目前的安全标准并不适合高密度低成本传感器节点。在这个项目中，一个高密度的自组织通信网络将被建模，在一组低成本的嵌入式处理器上进行仿真，并在受控条件下进行测试。将开发和验证高效的交换协议，以实现安全性并避免网络入侵。使用低功耗在公共网络上提供安全性的创新技术将使大规模部署低成本智能传感器节点成为可能。

Access to remote information has become ubiquitous. Sensors are deployed in wide variety of environments,including forested and mountainous areas, over the oceans, or in remote regions such as the Arctic. Also insitu wireless networks can be deployed for emergency situations. These networks rely typically on low costexpendable nodes. To enable data transmission over these ad hoc networks, a standard communication stack isprogrammed onto the nodes. This stack includes security features to avoid intrusion and disruption byundesired users. However, the current safety standards are not well suited for highly dense low-cost sensornodes. In this project, a highly dense ad hoc communication network will be modeled, emulated over a set oflow cost embedded processors, and tested in controlled conditions. Highly efficient exchange protocols will bedeveloped and validated to enable security and avoid intrusion over the network. Innovative techniques toprovide security over public networks using low power consumption will enable the deployment of low-costsmart sensor nodes at large scale.
