摘　　要：互联网存在着大量网络摄像头、PLC、传感器等物理设备,对这些设备进行自动发现有助于了解其分布和部署情况;从人机物多域融合的角度表示物理设备,有助于全面刻画物理设备,并为跨域攻击分析提供支持。文中提出一种基于网络协议报文和Web页面特征在互联网中发现物理设备的方法。该方法主要通过HTTP、SNMP和PPTP协议的握手报文头部信息和物理设备访问控制Web页面的结构特征发现物理对象并获取物理对象的基本信息,然后通过预置的产品信息库充分感知设备硬件信息,通过IP信息库获知设备物理地点和社会域属性,从而实现对物理对象的人机物多域融合分析。最后利用文中所提出的方法,开发了物理对象感知和分析系统Net Thing,并对运用文中方法获取的物理设备数据进行了分析和验证。There are many physical devices in the Internet,including webcams,PLC,sensors etc. Searching and finding these physical devices helps to knowmore about their distribution and deployment. Describing physical devices in＂social cyber physical multi- domain＂model is also good for fully depicting them and analyzing possible existence of cross- domain threats. A method for finding physical devices in the Internet based on the protocols＇ datagrams and Web page features is proposed. This method mainly uses the shake hands datagrams of HTTP,SNMP,PPTP and the features of Web pages to find physical devices and get their basic information. Then it expands hardware information of the devices through the products information base,and social domain information,such as location information,through the IP information base. At last,a proto type system named Net Thing is developed using method proposed,and the data of experiments is analyzed and verified.
