As logic locking becomes more sophisticated and new technologies emerge (e.g., laser probing for failure analysis), the statement "logic locking is dead" will become more common. While recent studies have investigated the possibility of defining a security metric(s) for logic locking, none are sufficient against all threat models and potential future threats. In this paper, we first examine the quantitative and qualitative metrics as a MUST for logic locking. Then, by establishing a bridge between metrics and the potential methods, we introduce a compound-style logic locking that can meet the criteria needed for logic locking based on the defined metrics.
