A trust management model based on platform environment security

In an open network environment, there are a large number of nodes with hidden danger or malicious behavior, which greatly reduce the network´s security and efficiency. Most of the existing trust models do not consider the platform security of the interactive node. In the proposed model, the node´s platform security is the context condition of nodes interaction; the nodes´ own interaction history and the recommendation from other nodes are synthetically taken into account when computing trust value. Simulation result shows that the model can effectively curb attacks from malicious nodes, reduce the risk when interact with dangerous nodes and strengthen the security of network system.
