Abstract

 

With the rapid development of smart grid technology, data security issues are gradually emerging, especially in terms of confidentiality. Although traditional encryption methods can protect the security of data, they often result in slow processing speed due to low encryption and decryption efficiency, and data is easily tampered with during transmission, posing a serious threat to the security and reliability of power data and the power system. In response to these issues, this article proposes an efficient power data sharing scheme based on Access Control Policy for Rewritable Blockchain Based onAccess Control Policy (RBACP).The immutability of blockchain makes power data more secure and transparent. The introduction of access control policies allows only those users who meet the permissions to make changes to data. This article implements an attribute-based
encryption This article implements an attribute-based encryption scheme for access control using identity-based signature embedding, resulting in attribute-based encryption for verifiable signatures (ABEVS), which strengthens the verification process, further avoids tampering, and improves data integrity. Finally, this article presents a specific example of RBACP and verifies its security and practicality through experiments and evaluations.

Keywords: smart grid; attribute-based encryption; rewritable blockchain; access strategy
