Abstract—Cloud computing, as a novel business model, has been paid more and more attention from academia and industry. The security issue of cloud computing is a key constraint for its applications. Some scholars studied the security issues of cloud computing from the viewpoint of trust. However, the past researches of trust mainly focused on the computation of trust degrees and overlooked the research of evolution of trust relationships. In addition, these research models could not completely adopt the environment of cloud computing. This article constructed a trust evolution model based on the trade evaluation mutually combined with the theory of interpersonal society trust relationship and characteristics of cloud services. Simulation was made on the Netlogo platform and the simulation results proved the model is reliable and effective. The model has a certain applied value.

Index Terms—cloud computing, cloud service, trust, evolution, simulation, the behavior similarity theory
