Abstract

An automatic protocol test method by reverse engineering from packet traces to extended finite state machine is disclosed. The method includes following steps: parsing the plurality of packets to extract a plurality of sessions; conducting a keyword analysis and a clustering algorithm to obtain protocol messages; initializing the protocol messages and merging equivalent states to obtain a finite state machine; extracting fields and values of the protocol messages to obtain a plurality of sub-datasets and adding a data guard and set of memories on the finite state machine to obtain the extended finite state machine.
