Abstract:

To develop secure routing technology for the current Internet, a trusted measurement model based on dynamic Bayesian networks(TMMDBN) is introduced by taking both node identity and its interaction into account. Combining the security authentication technology based on the combined public key(CPK), a new secure link state routing protocol(SLSRP) is proposed by applying the model to the OSPF protocol, which can determine a high security and trusted path for data transmission. Simulation results show that SLSRP achieves a much better security performance than OSPF with little increase in signaling overhead and computational complexity. Moreover, SLSRP has an adaptive capability and can quickly react to the denial of the service attack, which can effectively suppress the threat of an abnormal entity.

Key words: trusted measurement, Bayesian networks, combined public key, trusted platform module, network security
