Abstract


With the continuous advancement of Internet technology -based access control policy predicate has caused in privacy and Internet applications such as researchers, a lot of attention . Access control policies based on the predicate is very flexible and its predicate filters can also be very complex , which gives the strategy management administrator has brought great difficulties . In order to ensure access control policies based on predicates in a database management system (Database Management System, DBMS) in reasonably effective , the effectiveness of the policy and strategic relationship between conflict and redundancy analysis of issues such as the analysis and research . Gives access control policy based on predicate model and the effectiveness of a strategy based on this model , the conflict between effective strategies and tactics , redundant relations and other related definitions. Developed strategic analysis is the key to its filter predicate analysis and presents a strategy based on standardized analytical methods predicate . Through the analysis of policy filter types , predicates are given a standardized definition, design and implementation of the filter predicate canonicalization algorithm ; auxiliary list by generating solve the Boolean operators and symmetry generated by passing the problem . Combine predicates and auxiliary list rebellious nature , given the effectiveness of the policy analysis rules . To policy conflicts , for example, for different types of filter predicates , determine the rules given in a series of conflicts between the detection strategy based on the conflict between the predicate relations . The strategy is designed based DBMS general structure analysis system , including standardized module strategy , strategic effectiveness analysis module , strategic relationship analysis module and standardized policy cache module . To illustrate the strategic analysis methods DBMS performance impact , to reach for the realization of a dream Database 6.0 platform , adding strategic analysis subsystem , based on access control policy predicate analysis methods for performance testing. Final analysis method described strategy with low impact on system performance for DBMS strategy analysis and detection .
