Abstract: Flexible power trading is an important capability brought by smart grid to traditional electric distribution networks. Flexible power trading necessitates trust among smart grid entities, security and integrity for the transaction among entities for reliable power trading. In this work, a novel blockchain framework over internet of things enabled smart grid is proposed to facilitate secure and reliable power trading. Towards this aim, a cooperative trust-based reputation score model is proposed to provide reputation score to the entities. The communications between entities involved in power trading are authenticated using a three-party mutual authentication model. The transactions between the entities are integrity verified and secured in a blockchain framework. Use of blockchain provides an immutable storage for transactions and ensures consensus across all the entities involved in power trading, so that no entity can deny the participation in trading.

Keywords: authentication; blockchain; IoT; smart grid.
