摘要
物联网允许机器和设备之间互相连接,其应用程序不仅可以收集数据,还能够在任何时间、任何地点实现数据传输,因此物联网更易受到黑客攻击,数据的高噪声性也导致安全防御难度较高。为了提高物联网的主动防御能力,提出基于改进降噪算法的物联网攻击主动防御的方法。利用改进降噪算法优化物联网节点,从抗全局截获分析攻击能力、抗拒绝服务攻击能力和抗内部威胁能力三个方面分析物联网的薄弱点。采用基础防御信息和防御模式匹配算法,构建与物联网薄弱点相匹配的无线传感器网络病毒传播模型,实现物联网攻击的主动防御。实验结果显示,提出方法能够在1.6s内完成攻击防御,且对物联网数据的降噪效果显著,以上测试验证了说明研究方法的主动防御效率更高,应用性更优。
The Internet of Things(IoT)allows the interconnection between machines and devices.And it can not only collect data,but also realize data transmission at any time and anywhere.Therefore,the IoT is more vulnerable to hacker attacks.Due to the high noise of data,it is more difficult to make a security defense.In order to improve the active defense capability of the Internet of things,this paper puts forward a method for actively defending against IoT attacks based on an improved noise reduction algorithm.Firstly,the improved algorithm of noise reduction was adopted to optimize IoT nodes.Secondly,the weak points of the Internet of things were analyzed from three aspects:anti-global interception and analysis attack ability,anti-DoS attack ability and anti-internal threat ability.And then,basic defense information and defense pattern matching algorithms were used to build a virus propagation model of wireless sensor network matching the weak points of the Internet of things to realize the active defense.Experimental results show that the proposed method can complete the attack defense within 1.6s,and has a significant effect of noise reduction on the Internet of things data.The tests show that the active defense efficiency of the method is higher,and its application is better.
