Description The field of grammatical inference has been around for decades. These researches have resulted in numerous algorithms and dedicated data structures. Unfortunately, this work is often underused by security experts.

This presentation aims to illustrate the applicability of such algorithm, called L*, for the automated reverse engineering of communication protocols. I will briefly describe this algorithm and propose some feedbacks on how it can be used to actively infer the state machine of an unknown communication protocol.
