Trust Management in Space Information Networks

Authors:
Anders Fongen

Keywords: LEO satellites; trust management; space information networks; AaaS in space

Abstract:
The concept of a Space Information Network (SIN) is evolving from a satellite transport infrastructure towards a provider of a range of services, including even Application-as-aService (AaaS). Client endpoints connected to a SIN will invoke services in other connected endpoints, as well as services inside the SIN itself. Interactions taking place between clients and SIN components will create trust relations that must be protected from the usual threats. Traditional cryptographic protocols can offer adequate protection from some threats, but the particular conditions of a satellite network requires modifications of the methods used for authorization control and key management. The amount of connectivity and transport capacity required by a traditional Public Key Infrastructure (PKI) configuration causes excessive use of SIN resources, and a modified approach to key deployment, credential validation and authorization control should be investigated.
