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

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.
