A team from Trinity College Dublin and Intel Labs Europe deployed a delay-tolerant network (DTN) in remote areas of the Swedish mountains for six weeks during the summer of 2010. The network provided Web and email access for reindeer herders working 20 to 50 kilometers away from any power or communications infrastructure. Although this was definitely a less threatening environment than most Internet deployments face, the team still needed to address several security issues. In fact, such a network deployment is useful to analyze because the security problem is more bounded and hence easier to understand. This deployment's security aspects might also be useful for other researchers to consider when transitioning technology from the lab to the real world.
