Sharing Economy in Future Electricity Markets:Security and Privacy Analysis

This paper performs an in-depth security and privacy analysis of emergent (peer-to-peer) electricity trading markets where individual users (via their smart meters) can trade electricity with other users and market players in a (semi-)decentralised manner. Firstly, a high-level overview of future electricity markets is presented, and a comprehensive explanation is offered concerning the evolution of the current (and future)actors regarding their roles. Secondly, business model matrix analysis is deployed to develop and discuss in detail four scenarios based on customers’ information ownership and citizens’ level of involvement. Lastly, an analysis of security and privacy threats is performed which leads to a specification of necessary requirements to mitigate such threats. This paper provides and serves as a benchmark for risk assessment and future design of secure peer-to-peer electricity trading markets.
