Abstract
Disclosed is a method for identifying and parsing an industrial control protocol based on an industrial gateway. The industrial gateway captures, through a serial port and a network port, messages sent from a host computer and a lower computer to the industrial gateway, extracts features representing different protocol types and protocol fields from the messages, and identifies and parses the messages based on protocol character features.
