Abstract

UCON (Usage Control), a recent access control model, allows temporal control of the usage of permissions according to three criteria: Authorizations, oBligations and Conditions. In this paper, we investigate delegation in UCON and propose a new approach to achieve user-user total and partial delegations with the enforcement of constraints by taking advantage of UCON's existing components: Authorizations, oBligations and Conditions. The approach we propose can be modified and extended, without much effort, to other access control models accommodated by UCON and to a distributed environment.
