Protocol State Machine Reverse Engineering with a Teaching-Learning Approach

In this work, we propose a novel solution to the problem of inferring state machine an unknown protocol. We extend and improve prior results on Mealy machines, present new algorithm that accesses interacts with networked system runs protocol in order infer representing protocol's machine. To demonstrate viability our approach, provide implementation illustrate operation simple example protocol, as well two real-world protocols, Modbus MQTT.
