Abstract

Internet of Things (IoT) devices are becoming ubiquitous, and may be arranged to formformal or ad hoc Command and Control (C2) networks. Such networks typically do not have a mechanism to facilitate the sharing of either data or control inputs. This paper examines this problem in the context of IoT devices operating within C2 systems which do not have a trusted relationship with each other. We propose a solution which we call syndication, to provide a controlled mechanism to share data between C2 systems of devices without a fully trusted relationship. This paper builds upon previous work which established a lightweight protocol for secure C2 operations within the IoT. Using the proposed approach enables not only sharing of data but also permits the external controller to submit moderated requests for actions to be performed. The paper concludes by examining how this approach could also be adopted to provide secure guest access to connected systems in a domestic or commercial context.
