Concerns that quantum computing could place current encryption techniques at risk have been around for some time.
But now cybersecurity startup Active Cypher has built a password-hacking quantum computer to demonstrate that the dangers are very real.

Using easily available parts costing just $600, Active Cypher’s founder and CTO, Dan Gleason, created a portable quantum computer dubbed QUBY (named after qubits, the basic unit of quantum information). QUBY runs recently open-sourced quantum algorithms capable of executing within a quantum emulator that can perform cryptographic cracking algorithms.

Gleason explains, "[...] I hope that QUBY can increase awareness of how the cyberthreats of quantum computing are not reserved to billion-dollar state-sponsored projects, but can be seen on much a smaller, localized scale."

In response to the threat, Active Cypher has developed advanced dynamic cyphering encryption that is built to be quantum resilient.

Active Cypher's completely random cyphertext cannot be deciphered using even large quantum computers since the only solution to cracking the key is to try every possible combination of the key, which will produce every known possible output of the text, without knowledge of which version might be the correct one.

Active Cypher showcased QUBY in early February at Ready -- an internal Microsoft conference held in Seattle. The prototype will also be presented at RSA in San Francisco later this month.
