Abstract
The smart grid enables the bidirectional flow of electricity and data, but during multidimensional electricity consumption data reporting, Smart Meters (SMs) may compromise users’ privacy by disclosing detailed electricity consumption data from various devices. Additionally, in addressing the needs of diverse electricity Data Users (DUs), it is essential to protect their legal rights. Consequently, it is necessary to implement dimension-level access control for multidimensional aggregated data. However, existing Multidimensional Data Aggregation (MDA) schemes often fail to provide efficient dimension-level access control while safeguarding users’ privacy. To address these problems, this paper establishes a smart grid model based on fog computing and introduces a privacy-preserving MDA scheme with dimension-level access control. Specifically, our scheme utilizes the threshold Paillier cryptosystem and the Chinese Remainder Theorem (CRT) to securely aggregate users’ multidimensional data. Meanwhile, our scheme employs digital signatures to ensure data integrity and implements Key-Policy Attribute-Based Encryption (KP-ABE) to enforce dimension-level access control. Comprehensive theoretical analysis indicates our scheme satisfies privacy, integrity, and authentication. Extensive experimental results demonstrate our scheme achieves a trade-off between dimension level access control and system overhead.
期刊介绍:
The Journal of Systems Architecture: Embedded Software Design (JSA) is a journal covering all design and architectural aspects related to embedded systems and software. It ranges from the microarchitecture level via the system software level up to the application-specific architecture level. Aspects such as real-time systems, operating systems, FPGA programming, programming languages, communications (limited to analysis and the software stack), mobile systems, parallel and distributed architectures as well as additional subjects in the computer and system architecture area will fall within the scope of this journal. Technology will not be a main focus, but its use and relevance to particular designs will be. Case studies are welcome but must contribute more than just a design for a particular piece of software.
Design automation of such systems including methodologies, techniques and tools for their design as well as novel designs of software components fall within the scope of this journal. Novel applications that use embedded systems are also central in this journal. While hardware is not a part of this journal hardware/software co-design methods that consider interplay between software and hardware components with and emphasis on software are also relevant here.
