Research on Cloud Security Access Control Protocol for Power Marketing Services

With the acceleration of digital transformation in the power industry, power marketing information systems are increasingly relying on cloud computing platforms for data processing and service delivery. However, this trend also brings new security challenges, especially how to ensure secure access control for sensitive data. Attribute Based Encryption (ABE), as an advanced cryptographic tool, can provide fine-grained access control capabilities for data in cloud environments and has become an effective means of solving this problem. This article aims to study a cloud security access control protocol suitable for the field of power marketing, which utilizes attribute based encryption technology. Our research focuses on designing an efficient and secure access control scheme that can adapt to the characteristics of power marketing business while ensuring data privacy and integrity.
