- W4206965858 abstract "Aiming at the problem of the lack of effective access control for the source of access devices in the software-defined network (SDN), based on this, based on the ABAC model, a blockchain-based access control scheme for terminal access in the SDN network is proposed. First, the blockchain technology and ABAC mechanism are described, and the attribute-based access control model is formally defined; secondly, the access control architecture of the SDN network access terminal based on the blockchain technology is proposed, and the access control the basic framework and process of SDN are elaborated and analyzed in detail. Finally, an access control method based on smart contracts is used to achieve full-process transparent, dynamic, and automated access control for terminal access in the SDN network to ensure that the access control information cannot be tampered with. Auditability and verifiability. Finally, simulation experiments are conducted to verify the effectiveness of the scheme, which ensures the source of access equipment is safe and reliable and makes the SDN network safe and controllable. The research content is summarized and prospected." @default.
