Trust Model is an efficient wav to solve the trust problem in open network Since there are problems of dynamic adaptation.insufficient conglomerate of trust and consideration of incentive mechanism in trust quantization.this article presents a dynamic trust quantization model based on multi-factors in open network In the process of trust quantization the measurement of direct trust takes parameters of historical mutual information into consideration to raise the accuracv of direct trust quantization while the measurement of recommendatorv trust considers the bonus-penalty factor and reliabilitv of evaluation to guar antee the reliabilitv and efficiencv The measurement of integrated trust solves the weight problem between direct trust and recommendatory trust bv introducing balanced weight factor In the mutual process of network entities.the balanced weight factor changes dynamicallv according to the interactiveaccess times between network entities.which shows that the dvnamic adaptability The result of simulation experiment shows that.the method in this article has a better effect in resisting the active or passive attack from hostile nodes.decreasing the influence of recommendation from hostile nodes on trust quantization and guaranteeing the accuracv of trust quantization.
