【摘要】 水下传感器网络是一种新型的水下网络系统.文中分析研究了水下传感器网络面临的安全威胁、攻击和安全问题,结合水下环境和水下传感器网络特点,分析了严重威胁水下传感器网络的攻击.由于水下传感器网络和水声信道的特性,水下传感器网络易受各种恶意的攻击,特别是低成本的拒绝服务攻击会严重破坏网络的服务.现有的陆地传感器网络的安全策略不能直接移植应用到水下传感器网络,并且这些安全策略都是针对某一协议层,由于分层策略的缺点和限制,分层的安全策略不能有效防护混合攻击和跨层攻击,水下传感器网络应采用跨层安全体系结构.更多还原

【Abstract】 Underwater wireless sensor network(UWSN) is a novel type of underwater networked system.In this paper,we study the threat,attack,and security issues of UWSN.Moreover,we analyze attacks and threats which seriously influence UWSN.Due to the characteristics of UWSN and underwater channel,UWSN are vulnerable to malicious attacks.The existing security solutions proposed for terrestrial WSN cannot be used directly in UWSN.Moreover,most of these solutions are layer wise.Subsequently,we argue that layered security schemes cannot protect UWSN against blended attacks.Finally,we present a novel preliminary conceive,which is a cross-layer,adaptive,selective security scheme.更多还原
