In the open era of internet computing environment which is developing rapidly, aformation of the network system gradually becomes easy, through kinds of computingresources effectively integrated in distruction and heterogeneous. Besides, in the trustrelationships of the entity, it becomes more challenging and significant on how to accessto control other related issues effectively and safty, due to the wide field, dynamics andheterogeneous characteristics of limitation.In this paper, we mainly study the optimization problems for recommendation trustmodel in the dynamics of the network, our contributions are as follows:Firstly, through the research of dynamic network accessed to control rules and trustmanagements in the trust model, then qualitative and quantitative conditions which affectconfidences of entities are analyzed. The recommend trust assessment system isestablished based on the network.Secondly, the combination path-searching algorithm of recommendation trust whichis based on ant colony algorithm and swarm optimization algorithm is selected.Characteristics of network trusts are satisfied in the dynamic variation, from the researchesand applications about heuristic intelligent algorithm at home and broad.Finally, the main researching content of this paper is that the existing dynamic trustednetwork accesses to control that the used combination of new algorithm to optimize.Detailed problems are that a kind of improved heuristic algorithm is applied to correspondtrust model, and consider the distributed system and characteristics of information,combined with dynamic trust management model which are based on trust degreecalculation, as well as recommendation trust model is structural in dynamic network.Not only the model can solve more problems which is integrated information systemin large parts, wide variety and information sharing by often changing, but also realize toaccess to control effectively in different trust domains which is between the dynamic andsafety. At the same time, more security and effect assurances are provided for distributednetwork information system which accesses to control.
