Dynamic, non-interactive key management for the bundle protocol

Abstract

Secure, low-overhead key establishment is crucial to maintaining the high level of trust and security that are required many types of Delay Tolerant Networks. Existing schemes for key negotiation and exchange that are currently in use on the Internet often cannot scale to meet the environmental and technical constraints of many Delay Tolerant Networks. The few works presenting solutions to DTN key establishment have largely focused on targeted networking environments. This paper proposes a dynamic, and non-interactive scheme to facilitate secure communication in infrastructureless networks, supporting various levels of trust. Specifically, the solution presented in this paper provides a key management solution to opportunistic overlay networks using the Bundle Protocol.
