A Security Access Strategy for Sensitive Resource of Intelligent Production Line System with Dynamic Attribute Collaboration

Abstract

During the production and processing of the intelligent production line system of the Industrial Internet of Things (IIoT), it is easy to generate risks such as the unauthorized acquisition, tampering and unauthorized control of sensitive information by a third party in the communication. This paper propose and construct a dynamic attribute collaborative security access control strategy for sensitive resources of intelligent production line system in view of the risks and requirements of security access control of perceived information between intelligent production line equipment in the IIoT environment. Based on this strategy, a D-RSBAC (Dynamic-role&sensitivity based access control) model for intelligent production line system security is further established. This strategy realize the relative isolation of equipment processing control information on the basis of ensuring the overall performance of the communication system. This strategy allocate data access permissions dynamically based on roles and resource security levels to prevent sensitive information on the production line from being illegally obtained and tampered with by third parties during communications. This strategy can improve the security and reliability of information access effectively.
