DARPA seeks new use for SHIELD

The Supply Chain Hardware Integrity for Electronics Defense (SHIELD) programme, the Defense Advanced Research Projects Agency's (DARPA's) effort to stop the introduction of counterfeit parts into electronic systems, is partnering with IBM to create a way to verify and validate contracts.
SHIELD is a 100×100-micron-sized device. It has five special systems on it, including a full Advanced Encryption Standard (AES) 256 encryption engine and a microscopic antenna that can only be contacted using a small device that plugs into an iPhone. SHIELD has sensors that can detect any intrusion or compromise from ultraviolet or X-rays, excessive voltage, or temperature.

If an attempt is made to remove SHIELD from a package, it will self-destruct.
