Abstract: Hardware security is crucial for FPGA-based systems in addition to the functional realization of the system according to the expected specifications and optimal performance. FPGA has a longer supply-chain model that involves many entities. This results in greater opportunities for security threats and trust issues. Hardware Obfuscation is one method that can be used as a mechanism for a security effort from the threats of IP Piracy, Overbuilding, Trojan Hardware, Reverse Engineering, and Bitstream Modification. Obfuscation technique variations for FPGA-based system security cannot be fully implemented properly according to the specifications and limitations of the system design. To prevent and anticipate security threat attacks on FPGAbased systems, a performance analysis is needed to implement appropriate and effective techniques in system security. This paper discusses obfuscation techniques that can be implemented for security on FPGA-based systems according to the design process flow.
