Abstract: UCONABC is a basic framework of next generation access control policy Usage Control that is composed of Authorization-oBlige-Condition components, but so far it lacks of important delegation characteristic. The paper analyses the behaviors of delegation in UCON based on OM-AM engineering principles, presents a formalized usage control model with delegation features using BNF Extensions, called as UCOND, and further articulates its hybrid architecture based on Client & Server Delegation Reference Monitors and relative key protocol functions. UCOND is an extension model of UCONABC in the aspect of delegation authorization, and it resolves the delegation question of Usage Control Model. Moreover, we specify delegation procedure of an application for Digital Medium Resource Distribution System.

The UCONABC usage control model
Jaehong Park,Ravi Sandhu +1 more
TL;DR: This paper introduces the family of UCONABC models for usage control (UCON), which integrate Authorizations, oBligations, and Conditions (C), and addresses the essence of U CON, leaving administration, delegation, and other important but second-order issues for later work.
