Mobile nodes in some challenging network scenarios suffer from intermittent connectivity and frequent partitions e.g., battlefield and disaster recovery scenarios. Disruption Tolerant Network (DTN) technologies are designed to enable nodes in such environments to communicate with one another. A key feature of DTN technology is the late-binding capability that allows messages destined to a descriptive name to be resolved progressively until the messages are delivered to one or several recipients. In this paper, the authors describe a flexible security solution that allows messages destined to descriptive names to be sent securely such that unauthorized personnel is not allowed to eavesdrop on them. Their solution builds on the attributed based cryptography system.
