Study on security routing algorithm based on dynamic adjacent trust

Abstract

By studying the related issues of the router node trust,a dynamic adjacent credibility-trust model which inte-grates factors of state and behavior of the router node was proposed.On the basis of dynamic adjacent credibility-trust model,a security routing algorithm based on dynamic adjacent trust entropy was also proposed,which was validated in the OSPF protocol.The simulation results show that dynamic adjacent credibility-trust model can accurately reflect the state altering and malicious attack of the router node and has better dynamic response ability.In addition,the security routing algorithm can effectively guarantee the behavior and state trust of the router node with highly attack resistant properties.
