A Security Model for Online Accessing to Share Devices

Abstract

This paper analyzes and contrasts the difference between conventional access control objects and share device resources.It presents device resource characteristics,such as time-dependent permit diversity privilege,access capacity and process-dependent.According to the four key characteristics and role-based access control model,it introduces several concepts such as dynamic actor,permanent role and device access policy etc.A remote device access control(RDAC) model is presented.This model satisfies the requirement for describing online device and access control.
