Supply Chain Hardware Integrity for Electronics Defense (SHIELD)
Abstract
Counterfeit electronic components compromise business as well as defense systems, and pose a threat to the integrity and reliability of DoD systems. Detection of counterfeit components by current means is expensive, time-consuming, and of limited effectiveness. Maintaining complete control of the supply chain using administrative controls incurs substantial costs and has exhibited limited effectiveness. Current methods of detection involve a wide variety of techniques ranging from functional testing to physical inspections which may still miss certain classes of counterfeits. There have also been attempts by the semiconductor market to protect electronic components through the use of technology embedded in the component or its packaging. However, most of these methods are specific to a manufacturer's component and as such address only those issues critical to that manufacturer. Some methods can be circumvented, or require slow, expensive, off-site forensic analysis to verify authenticity. The Supply Chain Hardware Integrity for Electronics Defense (SHIELD) program will develop a technology capable of confirming, at any time and place, the authenticity of trusted parts, even after they have transited a complex global supply chain. SHIELD will prevent counterfeit component substitution by incorporating a small, inexpensive additional silicon chip ("dielet") within the Integrated Circuit (IC) package. The dielet will provide a unique and encrypted ID as well as anti-tamper features. The microscopic-size dielet embedded in the electronic component packaging will enable verification of a chip's identity from very close proximity.
