Abstract: This paper introduced a model for time-based temporal trust. The trust in multi-domain environment is uncertain, which is variation for various factors. Every domain is endowed with a trust vector, which figures the trust intensity between this domain and the others. hhe trust intensity is dynamic due to the time and the inter-operation between two domains, a method was proposed to ctuantify this change based on the mind of ant colony algorithm and then an algorithm for the transfer of trust relation was also proposed. Furthermore, this paper analysed the influence to the trust intensity among all entities that is aroused by the change of trust intensity between the two entities, and presented an algorithm to resolve the problem. Finally,we show the process of the trusts' change that is aroused by the time's lapse and the inter-operation through the Simulation Experiment.
