ACAC-OGF: Anonymous Certificateless Access Control Protocol for Digital Oil and Gas Field System Management Platform

The digital oil and gas field system applies digital communication technology to manage and optimize the development and production process of oil and gas field. The system realizes the comprehensive monitoring and intelligent management of oil and gas field by collecting, transmitting and processing various data of oil and gas field. However, in terms of data protection and access control, digital oil and gas field system is unable to ensure critical data confidentiality and provide trusted equipment authentication with efficient security mechanisms. To tackle with these challenges, this paper proposes a secure and efficient anonymous certificateless access control protocol for digital oil and gas field system management platform (ACAC-OGF), which implements anonymous identity authentication for the mobile engineering service terminal in the system, and ensures that only the legally authenticated mobile engineering service terminal can safely access the digital oil and gas field system management platform, thus ensuring authorized access of communication information. We conduct security analysis of ACAC-OGF, including message authentication, message confidentiality, identity anonymity, non-repudiation, traceability, unlinkability, and common attacks. We conduct performance evaluation of ACAC-OGF, the result shows that the protocol has lower computational costs and communication overhead, which demonstrates the feasibility of ACAC-OGF in the deployment of digital oil and gas field system management platform.
