Abstract :
Ontology, which is a conceptional model to describe conceptions and the relationships of conceptions, originates from philosophy, is not only static but also dynamic. In PKI, static characteristics of trust model which based on CA can not satisfy dynamic collaboration and uncertainty of environment. To deal with the problem, on the basis of dynamic characteristics of trust model and ontology, it is proposed to apply ontology to dynamic trust model in this paper, and an algorithm of constructing dynamic trust ontology is showed. Researches on the model indicate it have better dynamic adaptability, attack resistance, impartiality, convergence and expansibility.
