Abstract


With the continuous deepening of network information technology , especially the rapid increase in network applications , information security has become more and more attention of business users , access control technology as an important part of the management of access rights , and gradually get the attention of the majority of researchers . The fundamental task of access control is to prevent users from illegal use of system resources . Constrain the activities of the users in the system , such as the provisions users can perform which programs and which programs can not be executed , and by checking the access to authorized users access to resources , and to prevent risks to system security behavior , which can effective to prevent unauthorized users from accessing sensitive resources and legitimate users illegally use of resources. Access control technology and prototype systems research has a very important theoretical and practical value . In this paper, several existing access control technology for learning, research . Mastered the various concepts associated with the field of access control , more discretionary access control , mandatory access control , role-based access control , access control based on attribute -based access control , such as several technical advantages and disadvantages . XACML ( Extensible Access Control Markup Language ) is an OASIS organization can develop a extensible markup language , compared with other policy language , XACML policy language, which means that control access to information through the Internet by using XML language . -Depth understanding of the basic concepts of XACML , data flow , language model , and the introduction of Semantic Web technology, a Semantic Web and XACML - based access control model . As a result of the XACML access control mechanisms and Semantic Web technologies that the model has good versatility and scalability , and the access control model has a good semantic reasoning . The dissertation Hubei Province Natural Science Fund project funded 2009CDB100 .
