Trust Propagation Model in Pervasive Computing Environment

Trust is the fundamental building blocks in pervasive computing environment. In many ubiquitous application systems, trust quantification and propagation are the key issues to build successful architectures. According to the need of pervasive computing, some current trust propagation models are analyzed. In order to solve those problems, a definition of trust strength is proposed. And an improved parallelization algorithm is presented. A novel trust propagation model based on recommendation is proposed. Finally, a simulation testbed is built up to examine the trust propagation model.
