Industry includes more and more IoT components to have a better control on production and logistic processes.Unfortunately, growing network openness in a formerly isolated world induces major security risks which are especially critical in an industrial context. These risks are exacerbated by the highly fragmented nature of the industrial IoT market which imposes interoperability management and challenges security.We propose an approach to enable end-to-end data security within a heterogeneous IoT deployment. Interoperability is ensured by a central network powered by oneM2M interacting with various tier protocols. In this paper, we focus on secure communication with ZigBee and discuss how it can be transposed to other protocols, namely Z-Wave and Thread.
Industry 4.0 proposes the inclusion of IoT components in industrial contexts to have a better control on production and logistic processes.Unfortunately, growing connectivity in a formerly isolated world induces major security risks which are especially critical in an industrial context. Furthermore, the highly fragmented nature of the industrial IoT market imposes interoperability management. Interoperability and heterogeneity generally poses security challenges, exacerbating these risks.oneM2M is a promising standard that can enable interoperability and ensure communication with various tier protocols. The interface between oneM2M and tiers protocols has however to be trusted, which is undesirable. In this paper, we focus on the first phase of an approach to enable end-to-end encryption between oneM2M and Zigbee devices: secure key exchange. We fully define an exchange protocol taking place during the enrolment of a Zigbee device within oneM2M. We provide and discuss an implementation of this protocol, demonstrating its technical feasibility.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
