Title
Challenging issues of UCON in modern computing environments
Abstract
Usage CONtrol (UCON) is a next generation access control model enhanced with capabilities presented in trust and digital rights management. However, modern computing environments are usually introducing complex usage scenarios. Such a complexity results in involving a large number of entities and in utilizing multi party contextual information during the decision making process of a particular usage. Moreover, usage control is demanded to support novel access modes on single or composite resources, while taking into account new socio-technical abstractions and relations. In this paper, a number of challenging issues faced when UCON is applied in modern computing environments are highlighted through the utilization of representative usage scenarios. The results of this study are revealing various limitations in contextual information handling, lack to support complicated usage modes of subjects on objects, and weaknesses in utilizing information concerning previous or current usages of system resources.
