Transforming Energy Networks via Peer to Peer Energy Trading: Potential of Game Theoretic Approaches
Peer-to-peer (P2P) energy trading has emerged as a next-generation energy
management mechanism for the smart grid that enables each prosumer of the
network to participate in energy trading with one another and the grid. This
poses a significant challenge in terms of modeling the decision-making process
of each participant with conflicting interest and motivating prosumers to
participate in energy trading and to cooperate, if necessary, for achieving
different energy management goals. Therefore, such decision-making process
needs to be built on solid mathematical and signal processing tools that can
ensure an efficient operation of the smart grid. This paper provides an
overview of the use of game theoretic approaches for P2P energy trading as a
feasible and effective means of energy management. As such, we discuss various
games and auction theoretic approaches by following a systematic classification
to provide information on the importance of game theory for smart energy
research. Then, the paper focuses on the P2P energy trading describing its key
features and giving an introduction to an existing P2P testbed. Further, the
paper zooms into the detail of some specific game and auction theoretic models
that have recently been used in P2P energy trading and discusses some important
finding of these schemes.Comment: 38 pages, single column, double spac
Multilevel Threshold Secret and Function Sharing based on the Chinese Remainder Theorem
A recent work of Harn and Fuyou presents the first multilevel (disjunctive)
threshold secret sharing scheme based on the Chinese Remainder Theorem. In this
work, we first show that the proposed method is not secure and also fails to
work with a certain natural setting of the threshold values on compartments. We
then propose a secure scheme that works for all threshold settings. In this
scheme, we employ a refined version of Asmuth-Bloom secret sharing with a
special and generic Asmuth-Bloom sequence called the {\it anchor sequence}.
Based on this idea, we also propose the first multilevel conjunctive threshold
secret sharing scheme based on the Chinese Remainder Theorem. Lastly, we
discuss how the proposed schemes can be used for multilevel threshold function
sharing by employing it in a threshold RSA cryptosystem as an example
