Abstract

RBAC(Role Based Access Control) is an access control method based on the user's roles and it provides more flexibility and applicability on the various computer and network security fields than DAC(Discretionary Access Control) or MAC(Mandator Access Control). In this paper, e newly propose ERBAC\ulcorner(Extended RBAC\ulcorner) model by considering subject's and object's roles and security levels for roles additionally to RBAC\ulcorner model which is firstly proposed by Ravi S. Sandhu as a base model. The proposed ERBAC\ulcorner model provides finer grained access control with multilevel security on he base of subject and object level than RBAC\ulcorner model.
