Interface access control graph neural network method for flexible automation production of mine ventilation duct (opens in new tab)

Interface authorization in flexible automated mine ventilation duct production lines is difficult because heterogeneous users and services access safety-critical resources under time-varying cyber-physical risk that static RBAC/ACL rules cannot capture. This study presents HGRAD, a heterogeneous-graph risk-adaptive access control framework for industrial cyber-physical systems. HGRAD models each access event as a dynamic graph with four node types: user nodes encode operator identity, role, a...
