DTN Security Key Management - Requirements and Design
JPL, Calif. Inst. Of Technology
Delay/Disruption Tolerant Networking (DTN) introduces a network model in which communications may be subject to long delays and/or intermittent connectivity. These challenges render traditional security key management mechanisms infeasible since round trip delays may exceed the duration of communication opportunities. This document therefore proposes requirements and outlines a design for security key management in DTNs.
