As control logics are frequently implemented using finite state machines (FSMs), integrating obfuscation techniques into the FSM design is paramount. Prior research has leveraged diverse flip-flop configurations, changing the flip-flop type during the FSM execution, to confuse potential attackers. Building upon the previous work, this paper introduces the integration of an obfuscation mode, thereby bolstering FSM security through the simultaneous application of obfuscation modes and diverse flip-flop configurations. Experimental results consistently confirm the feasibility of our approach.
