Blockchain-Oriented Data Exchange Protocol With Traceability and Revocation for Smart Grid

Abstract

<p>The smart energy system (SES) encourages data administration and information services developments, particularly smart grids. Presently, numerous SESs cloud environments are accessible to smart grids. Nonetheless, because of the semi-credible character of the SES cloud environments, achieving secured access, information storage, updates, deletion, tracing, and revocation of ill-disposed clients is a genuine concern. In this publication, an Ethereum blockchain-oriented secured access regulation design upholding traceability and revocability is offered for smart grids to resolve these problems. The blockchain implements unified identity verification and saves all public-keys, users’ attribute sets, and revocable lists. The system administrator creates system parameters and sends private-keys to users. The domain administrator prepares the domain’s security and privacy-preservation policies and executes encryption procedures. If the attributes correspond with the access policy and the user’s ID is unrevoked, they could acquire interim-decryption capabilities from the edge/cloud servers. Tracking malevolent users for revocation is applicable throughout all stages, ensuring the system is secured under Decisional-Bilinear-Diffie-Hellman (DBDH) complex theory and can withstand multi-attacks. Analysis revealed the size of the public/private keys to be shorter, contrary to relevant schemes. The overhead duration is less for generating the public-key, data encryption, and decryption phases. </p> <p> </p>
