Toward a Distributed and Autonomous DTN Security Environment

This document surveys existing terrestrial network security practices, focusing on public key infrastructure with X.509 (PKIX), and identifies ways that the existing systems and protocols can be used in a delay-tolerant networking (DTN) environment. Additional discussion of protocols currently under development shows how PKIX security can be used directly and efficiently within a DTN. These are combined into one possible vision for distributed and autonomous security within the existing LunaNet architecture.
