Smart Grid Communications: Overview of Research Challenges, Solutions, and Standardization Activities
Optimization of energy consumption in future intelligent energy networks (or
Smart Grids) will be based on grid-integrated near-real-time communications
between various grid elements in generation, transmission, distribution and
loads. This paper discusses some of the challenges and opportunities of
communications research in the areas of smart grid and smart metering. In
particular, we focus on some of the key communications challenges for realizing
interoperable and future-proof smart grid/metering networks, smart grid
security and privacy, and how some of the existing networking technologies can
be applied to energy management. Finally, we also discuss the coordinated
standardization efforts in Europe to harmonize communications standards and
protocols.Comment: To be published in IEEE Communications Surveys and Tutorial
BlockChain: A distributed solution to automotive security and privacy
Interconnected smart vehicles offer a range of sophisticated services that
benefit the vehicle owners, transport authorities, car manufacturers and other
service providers. This potentially exposes smart vehicles to a range of
security and privacy threats such as location tracking or remote hijacking of
the vehicle. In this article, we argue that BlockChain (BC), a disruptive
technology that has found many applications from cryptocurrencies to smart
contracts, is a potential solution to these challenges. We propose a BC-based
architecture to protect the privacy of the users and to increase the security
of the vehicular ecosystem. Wireless remote software updates and other emerging
services such as dynamic vehicle insurance fees, are used to illustrate the
efficacy of the proposed security architecture. We also qualitatively argue the
resilience of the architecture against common security attacks
