Secure Access and Routing Scheme for Maritime Communication Network

This paper proposes a transmission scheme to ensure the maritime communication security, which includes access rules, routing selection scheme, and power allocation mechanisms. The access rules and the routing selection utilize the automatic identification system (AIS) information to choose the secure access points and routing links to prevent eavesdropping, and the power allocation limits the leaked information by means of reducing the received signal power of the eavesdroppers. The simulation results show that the intercept probability of the proposed scheme decreases by about ten to the negative two power compared with that of the contrastive scheme, and the recovering proportion for eavesdropper is less than 0.2. In addition to above, the secrecy capacity of the proposed scheme achieves about 6.8% improvement compared with the baseline scheme.
