Abstract: Trust is the most important problem for Internetware entities interaction and collaboration. Traditional trust models have problems of large overhead and slow convergence in large-scale and complex network environments. In order to address these problems, this paper puts forward a trust model for Internetware based on complex network, introduces the characteristics of small-world and scale-free of complex network into this model, and elaborates the model’s definition, structure, trust computation rules and proof for its dynamic evolution. PeerSim simulation results show that the adoption of complex network concepts into Internetware helps to reduce the trust chain length and the amount of network messages, accelerate the convergence rate of trust, and provide valuable new ideas to resolve trust issues of Internetware in large-scale distributed networks.
