Safety analysis of effect among mutable attributes in usage control
LI Pei-wu · Journal of Nanchang Institute of Technology · 2009
Update effect among mutable attributes contributes greatly to the expression of application in usage control mode,but it also causes a series of security problems.This paper first defines effect-among-attributes graph,and expresses effect rule of attributes in it,which resolves the update problem of mutable attribute affected by other attributes.It then analyzes the effect among mutable attributes based on time sequence of update,and puts forward relevant effect rules to resolve security problems of effect among mutable attributes.
