Smart grid leverages distribution networks and intelligent transmission techniques to advance the delivery of electricity, with a primary focus on enhancing reliability, security, and efficiency. This advancement is realized through bidirectional data exchange for consumption monitoring and operation optimization within the electrical system. Smart grid infrastructures commonly depend on precise monitoring of electrical system parameters to enhance the reliability and robustness of the grid. It is crucial to underscore the significance of maintaining data integrity while disseminating these measurements across diverse grid stakeholders over expansive network infrastructures. In this paper, we propose a lightweight privacy-enhanced secure data sharing scheme for the smart grid, which not only ensures that only authorized users in the smart grid can efficiently access the smart grid data, but also prevents sensitive information leakage from the access policies revealing about the protected data, data owners, or recipients in smart grid. Besides, we also present strict security proofs to prove the resistance to chosen-ciphertext attacks (CCA). Finally, some efficiency analyses are made to indicate the most prominent energy-efficiency our scheme enables.
