摘要
近几年来,水下无线传感器网络作为一种新型的网络模式被广泛应用于海洋探索、监测和保护中.水下无线传感器网络由大量部署在监测区域内的微型传感器节点、静态或动态水下机器人组成,它们通常使用声信道进行通信.由于声通信信道传输速率低、误码率高、高延时和信道窄的独特特性,使得水下无线传感器网络特别容易受到一些恶意攻击.此外,在这些应用中需要考虑的一个基本问题就是安全问题.主要阐述了水下无线传感器网络的安全要求,分析了水下无线传感器网络的安全现状及应对方法,并提出了一些尚待解决的安全问题.
In recent years, underwater wireless sensor networks(UWSNs) has been widely used in ocean exploration, monitoring and protection. UWSNs as a new type of network mode consists of a large number of small sensor nodes, static or dynamic underwater robots deployed in the monitored area. They usually use acoustic channels for communication. Due to the unique properties of low transmission rate and high bit error rate, high delay and narrow channel,UWSNs is particularly vulnerable to malicious attacks. Besides, these applications need to consider a basic question that is security problem. This paper mainly describes the security situation and countermeasures, analyzes the security requirements of UWSNs, and puts forward some security problems which remaining to be solved.
