The Logic of XACML
We study the international standard XACML 3.0 for describing security access control policy in a compositional way. Our main contribution is to derive a logic that precisely captures the idea behind the standard and to formally define the semantics of the policy combining algorithms of XACML. To guard against modelling artifacts we provide an alternative way of characterizing the policy combini...

متن کاملdesign of an analog fuzzy logic controller chip
fuzzy logic has been developed over the past three decades into a widely applied techinque in classification and control engineering. today fuzzy logic control is one of the most important applications of fuzzy set theory and specially fuzzy logic. there are two general approachs for using of fuzzy control, software and hardware. integrated circuits as a solution for hardware realization are us...
15 صفحه اولOffline Expansion of XACML Policies
In the last few years XML-based access control languages like XACML have been increasingly used for specifying complex policies regulating access to network resources. Today, growing interest in Semantic-Web style metadata for describing resources and users is stimulating research on how to express access control policies based on advanced descriptions rather than on single attributes. In this ...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
