【Abstract】The smart energy system (SES) encourages data admin-istration 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, dele-tion, tracing, and revocation of ill-disposed clients is a genu-ine concern. In this publication, an Ethereum blockchain-ori-ented secured access regulation design upholding traceability and revocability is offered for smart grids to resolve these problems. The blockchain implements unified identity ver-ification 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 ad-ministrator prepares the domain's security and privacy -pres-ervation 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 capabil-ities from the edge/cloud servers. Tracking malevolent users for revocation is applicable throughout all stages, ensuring the system is secured under Decisional-Bilinear-Diffie-Hell-man (DBDH) complex theory and can withstand multi -at-tacks. Analysis revealed the size of the public/private keys to be shorter, contrary to relevant schemes. The overhead dura-tion is less for generating the public-key, data encryption, and decryption phases.
