摘要：Trust is the key for an information system to make security decisions. There does not exist in an aforehand trust relationship among principals in dynamic systems. To secure transaction, trust relationship must be established in principals. However, the existing trust architectures are flat, so they cannot embody well the dynamic characteristic of trust and do not take on well operability. In this paper, a two-layer trust architecture for dynamic systems is presented. Trust in this model is composed of a basic trust layer and a dynamic trust layer. Basic trust depends on the attributes of a principal, recommendation, or experience, while dynamic trust relies on the application context. This trust structure can reduce the complexity of making a decision in dynamic system.
