Passive worm, a serious risk to multimedia sharing environment, has drawn much attention because of its undetectable, destructive, and wide-ranging features. Existing propagation models for passive worm only noticed its similarity to biological viruses in propagation, ignored the impact of social attributes of P2P nodes on the spread of worms. This paper proposes a defense model of passive worm in multimedia sharing environment. The contributions made in this paper include four aspects. First, we analyze the deficiency of current defense model of passive worm based on mean-field theory in multimedia sharing environment. Second, we build a node evaluation system based on trust relationship. Third, we develop a defense model based on game theory. Fourth, we provide extensive numerical study and simulation experiments to the impact of some relevant model parameters on the defense of passive worm in multimedia sharing environment. The model presented in this paper is applicable for defending against passive worms in multimedia sharing environment.
