Security analysis on underwater acoustic networks

From the point of view of the defending side, UAN will be a serious threat for its strong functionality (long range and high precision) of surveillance and detection. Therefore, countermeasures must be taken to weaken its effect. It is rational trying to destructing the protocol of the network, so that the network would not engage the cooperation of the nodes. That is to say, the network would degrade to a collection of individual sensors. The features of UAN, including its operation environment, are analyzed, and the differences between UAN, WSN and ASN are investigated, focusing to their different security demands and adopted measures. It shows that interfering to UAN will be a disaster for the networking. But on the other hand, there are many challenges. The vulnerability and potential security factors of UAN are studied thereafter.
