µKMS: micro Key Management system for WSNs
IET Wireless Sensor Systems, 2018Co-Authors: Sofiane Aissani, Mawloud Omar, Abdelkamel Tari, Feriel BouakkazAbstract:Key Management is the basic building block of all the security protocols and is one of the most challenging issues in wireless sensor networks (WSNs). Centralising a trusted Key Management server is not an appropriate solution in such fully distributed networks. On the other hand, designing a distributed Key Management system is a challenging task, due to the constrained characteristics of sensor nodes, which are limited in storage, computation, communication, and energy. In the literature, there is a hot research effort on Key Management purpose for WSNs. The greatest part of the existing solutions focuses mainly on the optimisation of the Key number, reKeying frequency and process or the encryption system of the distributed Keys. Unfortunately, these systems are implemented as an additional and independent service, involving a considerable overhead. In this study, the authors propose µKMS (micro Key Management system) for WSNs. µKMS implements a dissimulation scheme, embedding the reKeying process messages on the unexploited coding space of the exchanged ZigBee packets. They have developed simulations, where the obtained results show the relevance of µKMS in terms of communication overhead, storage overhead, and energy consumption.

Distributed Key Management in Microgrids
IEEE Transactions on Industrial Informatics, 2020Co-Authors: Vaios Bolgouras, Emmanouil Panaousis, Christoforos Ntantogian, Christos XenakisAbstract:Security for smart industrial systems is prominent due to the proliferation of cyber threats threatening national critical infrastructures. Smart grid comes with intelligent applications that can utilize the bidirectional communication network among its entities. Microgrids are small-scale smart grids that enable machine-to-machine (M2M) communications as they can operate with some degree of independence from the main grid. In addition to protecting critical microgrid applications, an underlying Key Management scheme is needed to enable secure M2M message transmission and authentication. Existing Key Management schemes are not adequate due to microgrid special features and requirements. In this article, we propose the Micro sElf-orgaNiSed Management (MENSA), which is the first hybrid Key Management and authentication scheme that combines public Key infrastructure and web-of-trust concepts in microgrids. Our experimental results demonstrate the efficiency of MENSA in terms of scalability and swiftness.

Besides protecting critical microgrid applications, an underlying Key Management scheme is needed to enable secure M2M message transmission and authentication. Existing Key Management schemes are not adequate due to microgrid special requirements in comparison to traditional networks, while existing schemes intended for the smart grid present weaknesses. We propose the Micro sElf-orgaNiSed Management (MENSA), which is the first hybrid Key Management and authentication scheme that combines Public Key Infrastructure (PKI) and Web-of-Trust concepts in microgrids. The experimental results to demonstrate the efficiency of MENSA in terms of scalability and swiftness.
