The Design And Reseach Of Security Service Control Model In Security Middle Ware

With the rapid development of the information technology, users from different region or department with different requirements exchange data through Internet. Security leak in Internet gives the chance of wire tapping, forgery and sophisticating to attackers, Security has become the bottle-neck of information development nowadays. As combination of security technology with middleware technology, Security middleware was brought up to meet the requirement. with the multilayer frame, it can shield the difference of material security service transfer, and providss uniform flat roof for sorts of security services. This paper based on this background, provided a new security service dynamic management of security middle ware , implemented a policy of the uniform management of the multi security service in security middle ware.Firstly, by researching on the basic theory of security such as security middleware, cryptograph theory and figure certificate, this paper bring forward a new three-layer model which suitable for the security middle ware used in wireless network,and then give a particular design to the security service control model,security service programming interface and resource configration,after this,this paper gives a design and implement to the dynamic management policy of the security services.The OOP technology was widely used in this system,it conquers the disadvantage of low use of system resource,security service transfer in high frequency,the usability is bad in traditional security middle ware system by the dynamic management policy.Finally,there is a test and data analyse of the function given by the security services control model and the policy of dynamic management.The result tells us that the security middle ware given in this paper could provide many kinds of security services,it could satisfy the requirements of different users with different level of security services.It optimizes the useof system resource in wireless network and ensure the system capability.It has the advantage of easy to expansion,repeat useable,transplantable,high use ratio of resource.
