无线传感器网络的安全问题已经受到广泛关注,特别在其进入工业控制领域及军用领域后,但典型的传感器节点设计受计算能力、存储能力及无线链路的频带宽度限制,这些限制导致无法设计更为完善及复杂的安全策略.工业用传感器很多情况下可使用有源电力供电或太阳能供电,所以传感器设计上一般具有较强的计算能力及电池续航能力,在针对无线传感器网络的攻击行为中只有部分会对其网络产生巨大影响,微型传感器所存在的一些针对能量或计算能力的攻击模式基本无法有效影响工业上使用的传感器.本文针对这些特点分析了一些热点研究的安全技术,并探讨了工业用无线传感器网络安全的进一步研究方向.%Security issues of wireless sensor networks have attracted widespread attention,especially after it enters the field of industrial control and military areas.While typical sensor node design is restricted by computing power,storage capacity and frequency bandwidth of wireless link,these restriction make it unable to design more sophisticated and complex security policies.Active power or solar power can be supplied to industrial sensor in many cases,so the sensor is generally designed with strong computing power and battery life.Among the attacks against wireless sensor networks,only a few of them will have a great impact on its network.Some attack patterns of micro-sensors which is against the energy or basic computing power,can not effectively impact industrial sensors.This article analyzes some of these characteristics and hotspot security technology,and discusses the direction of further research of industrial wireless sensor network security.
