摘　　要：为了获取物联网表通信协议的协议规范,本文提出一种基于关键字段的协议状态机推断方法,并以协议命令码字段作为状态相关字段。通过捕获物联网表协议原始数据,获取关键字段,并构建三个步骤,最终生成物联网表协议状态机。实验表明:与EDSM方法和ReFSM方法相比,该方法生成的协议状态机模型具有更高的准确性和更快的响应速度。In order to obtain the protocol specification of iot table communication protocol,this paper proposes a protocol state machine inference method based on key fields,and takes protocol command code fields as state related fields.By capturing the original data of iot table protocol,obtaining key fields,and constructing three steps,the iot table protocol state machine is finally generated.Experiments show that compared with EDSM method and ReFSM method,the protocol state machine model generated by this method has higher accuracy and faster response speed.
