ABACPR: Attribute-Based Access Control Supporting Policy Reconstruction for Intent-Based Networking

With the rapid advancement of Internet of Things (IoT) and the growing complexity of network infrastructures, the traditional network management model based on manual configuration is no longer able to meet the dynamic IoT secure communication requirements. Intent-based networking (IBN) significantly improves network manageability and agility by driving network automation through high-level business intent. However, policies in IBN are highly dynamic, and issues such as frequent changes in user intent, role or attribute adjustments, and ad-hoc access requirements in multi-tenant environments make it necessary for the system to quickly adapt to policy changes to ensure secure data sharing. Attribute-based encryption has become a key enabler for securing IoT communications, offering fine grained access control and adaptability to users’ dynamic access requirements in real time. In this paper, we propose an attribute-based access control supporting policy reconfiguration (ABACPR) for the highly dynamic nature of policies in IBN, aiming to improve the flexibility and efficiency of policy updating and ensure the security and consistency. Finally, We compared the theoretical and experimental analysis with related works and the results demonstrate that ABACPR is better suited for secure IoT communication in IBN.
