Analysis method and device for multi-version communication protocols and storage medium

The embodiment of the invention provides an analysis method and device for multi-version communication protocols and a storage medium. The technical problem that an existing multi-version communication protocol analysis method wastes a large number of analysis resources is solved. The method comprises the following steps: dividing initial rules in a multi-version communication protocol into a plurality of initial rule sets; determining a difference rule set and a same rule set in the plurality of initial rule sets, and determining a first rule set based on the difference rule set; generalizing the initial rules in the first rule set to obtain a second rule set; instantiating the second rule set based on an instantiation parameter corresponding to a to-be-analyzed communication protocol version stored in a preset difference rule parameter library to obtain a to-be-analyzed difference rule set; and enabling the protocol analysis model to analyze the to-be-analyzed difference rule set and the solidification rule
