Ts-RBAC: A RBAC model with transformation
G Liu, R Zhang, H Song, C Wang, J Liu, A Liu - Computers & Security, 2016 - Elsevier
The traditional role-based access control (RBAC) model is typically static, ie, permissions
are granted based on a policy that seldom changes. A more flexible support for access …
