中文摘要：
This paper presents a novel trust model based on multiple decision factor theory(MDFT)and a trust routing algorithm based on MDFT to exactly evaluate routing node trust and establish a trustworthy routing path.MDFT integrates four dimensional trust decision factors including behavior,state,recommend and node liveness to realize an exactly finer-grained trust evaluation.On the basis of MDFT,a trust routing algorithm is presented and validated in open shortest path first(OSPF)protocol.Simulation results show that the algorithm can reflect the routing node trust accurately and has better dynamic response ability.Under the circumstance of existing deceptive nodes,the algorithm has better anti-deception performance and higher attack node detection rate than conventional algorithm.

This paper presents a novel trust model based on multiple decision factor theory （MDFT） and a trust routing algorithm based on MDFT to exactly evaluate routing node trust and establish a trustworthy routing path. MDFT integrates four dimensional trust decision factors including behavior, state, recommend and node liveness to realize an exactly finer-grained trust evaluation. On the basis of MDFT, a trust routing algorithm is presented and validated in open shortest path first （OSPF） protocol. Simulation resuRs show that the algorithm can reflect the routing node trust accurately and has better dynamic response ability. Under the circumstance of existing deceptive nodes, the algorithm has better anti-deception performance and higher attack node detection rate than conventional algorithm.
