Focusing on the file pollution problem exists in unstructured P2P file sharing systems, we propose a strategy named TrustIs by combining the trust mechanism and the immune strategy of complex network to resist the propagation of polluted files. With the help of peer reputation, trusted immune peers and backup peers can be screened out. Also, the files and indices can be identified based on their object reputation and index reputation so as to provide reference for immune pees to filter out the polluted files or indices. Meanwhile, an immune token ring network is set up for monitoring peers’ behavior and implementing the refreshment of the immune resources. The results of the simulations show that TrustIs can effectively resist the propagation of polluted files.
