Protected core networking: communications challenges in tactical environments

Protected Core Networking (PCN) concepts are seen as key elements to securely automate the deployment and management of federated coalition networks. However, the extension of PCN principles to the tactical domain is not trivial. Indeed, it encompasses challenges that contest the notion that PCN and its interfaces are agnostic to the communications bearer. In this paper, we address the tactical environment idiosyncrasies, the particularities of its communications and their ability to support PCN concepts. Complementary, we present architectural options for integrating PCN into the tactical and discuss their open challenges and ways forward.
