Security is rapidly becoming a critical factor in the IC design and test cycle. To provide higher levels of assurance and trust to designers, manufacturers and end users of integrated circuits (ICs), there is a need to integrate security measures during design, validation, and manufacturing test covering all aspects of security threats in hardware. These threats include secret information leakage, malicious hardware modifications in an untrusted foundry, hardware IP piracy and reverse engineering efforts. This session will have three presentations focusing on the design, validation, and test challenges for attack-resistant secure hardware systems.
