A distributed trust model is proposed based on multi-factor trust.The proposed trust model introduces an aging function to distinguish the importance of trust in different time.When calculating the comprehensive trust value of nodes,the model increases the trust of energy by analyzing the residual energy of node.Also,the model combines the trust of communication and the trust of energy and properly adjusts the size of the weight between communication trust and energy trust to evaluate the credibility of sensor nodes.Simulation experiment and analysis shows that this model can quickly identify malicious nodes with improves successful rate of trading by nodes and security of information in the network system when compared with other models.

Key words: wireless sensor network;trust model;aging function;security
