Research On The Association Of Concurrent Access Requests And The Method For Access Control Coordination

With the rapidly development of network applications, the interface content ofnetwork applications are consisted from access control objects with different securitypolicies. During the accessing process to the resources, applications will produce alarge number of concurrent access requests. The absence of unified access controlwithin these access requests will lead to Information disclosure of the Securityprivacy information.Access control information systems as an important protection method arecommonly used in operating systems, databases and applications. With a high degreeof application integration, rapid development of cloud computing and distributedtechnologies, conventional access control policies using a single method cannot meetthe security requirements now. Access control model need to be improved inconcurrency, flexibility, coordination management, and scalability aspects.This paper investigated the construction and linkages association of the parallelaccess requests in current network applications and put forward the definition thatcombined with the description of Discrete Mathematics on relationship. This paperalso put forward the theorem of access requests association.This paper proposed forward the overall structure of the access controlcoordination method which based on the access control models and satisfied theconcurrency, flexibility and coordination management aspects. This paper alsopresented the working modes of each part to fit the concurrent access requests to meetthe functional requirements of obtaining information, resources and services. On thebasis of the above relationship association, the paper also proposed an algorithmlooking access requests as access diagram nodes that constructs access diagrams. Inthe algorithm objects send access requests according to the relationship and securitylevel that effectively reduced the transmission of non-secure access requests, fasterthe loading of application interface.This paper designed and achieved a solution of access control coordinatedmechanisms. This paper achieved a resource management system for managing accesscontrol object relationship data sources of relational data resource and realized webservice on Rest model for providing concurrent access requests relationship data. Thispaper also achieve the access control coordinate mechanism in the web application front with web page sending access request in accordance according to therelationship and security level, reasonable scheduling access request, that schedulingaccess request more reasonable. Based on asynchronous communication andmulti-threading technology, the method ensured the system’s concurrency and safetyand also optimized the application interface to provide users with better performanceexperience.
