Researchers at Xerox PARC accept created a new type of cryptographic processor that'due south capable of self-destructing if ordered to do then. The new chip is office of a DARPA-funded security button to create ways of safeguarding summit hugger-mugger information that are less susceptible to hacking if they fall into the wrong hands.

Creating a scrap that tin can store cryptography keys and self-destruct if it falls into the wrong hands could solve a trouble that'south as onetime as cryptography itself — how do yous ensure that the right recipient can read your messages, while yet protecting the data from unauthorized recipients? Quantum computing could offer a potential solution to this in the long run, since attempting to read the information being transferred between two quantum computers volition inevitably change the data-state and alert the users that they are being spied on. Since quantum computing remains a long mode off, withal, other solutions for data security are needed.

This is where the Xerox PARC processor comes in. The flake is built on a Corning Gorilla Glass substrate and designed to shatter if ordered to do so.

"The applications nosotros are interested in are data security and things like that," said Gregory Whiting, a senior scientist at PARC in Palo Alto, California. "We really wanted to come up with a system that was very rapid and compatible with commercial electronics."

"We take the glass and we ion-commutation atmosphere information technology to build in stress," said Whiting. "What you get is glass that, because it's heavily stressed, breaks it fragments into tiny little pieces.

Shattering the glass is straightforward. When the proper circuit is toggled, a small resistor inside the substrate heats up until the glass shatters. According to Corning, it will continue shattering even after the initial break, rendering the entire chip unusable. The demo fleck resistor was triggered past a photo diode that switched the circuit when a laser shone upon it. The glass plate quickly shattered into fragments once the laser touches information technology.

By storing a cryptographic key inside the Gorilla Glass substrate, a device could theoretically be locked downwardly securely, even in hostile territory. The diode could also be triggered by radio or by a simple mechanical switch. There's no word yet on commercialization or integration into existing devices, just if the substrate proves secure enough to protect the chip against drops or falls, nosotros might come across armed services systems adopt this kind of approach to meliorate cryptographic security.
