IP providers are in pressing need of a convenient means to track the illegal redistribution of the sold IPs. An active approach to protect a VLSI design against IP infringement is by embedding a signature that can only be uniquely generated by the IP author into the design during the process of its creation. a VLSI IP is developed in several levels of design abstraction with the help of many sophisticated electronic design automation tools. Each level of design abstraction involves solving some NP-complete optimization problems to satisfy a set of design constraints. In this paper, a new dynamic watermarking scheme is proposed. The watermark is embedded in the state transitions of FSM at the behavioral level.
