Quantum Safe Technology

Overview

QuintessenceLabs’ data protection integrates unique quantum capabilities to deliver the most trusted level of security today, while preparing for tomorrow’s quantum computing threat.

Our world-leading quantum random number generators already deliver the assurance of the highest quality keys.  And our quantum key distribution will soon allow you to securely exchange keys, even when quantum computers break current key exchange protocols.

Quantum Random Number Generators

Challenge

Most security applications use Pseudo-Random Numbers to generate keys. These are generated from a short random seed using deterministic algorithms. They are not truly unpredictable, and have resulted in many security issues.

True Random Number Generators (TRNG) use random physical processes to generate random numbers.  Some are better than others. “True” Random Numbers based on deterministic systems can be predicted if enough is known about the system, or if they can be influenced by actions such as temperature changes.

Our Technology

True Random Numbers generated using quantum physics, called quantum random number generators (QRNG), can be truly random.

Most available quantum random number generators are based on the detection of single photons and have limited throughput. This may result in operational constraints regarding key rotation or number of keys for example.

QuintessenceLabs uses quantum tunneling to deliver truly random numbers at 1Gbit/s, with flexible form factors and compelling costs, to enable practical, large-scale security and other applications.

Quantum Key Distribution

Challenge

Key distribution is the process of sharing encryption keys.  We typically use public key ciphers, such as RSA, Diffie-Hellman and ECC, to share symmetric keys that can then encrypt or decrypt data.

This is threatened by weak keys, increased processing power, new attacks, and quantum computers. In just a few years, quantum computers will break these ciphers, preventing us from securely exchanging information.  Even now, data encrypted today may well be intercepted and stored for future decryption by quantum computers.

Our Technology

Quantum Key Distribution (QKD) protects data using the laws of physics, making it secure against advanced attacks, in particular quantum computers.

QuintessenceLabs is a leader in the development of QKD. qOptica will all but eliminate the risks of key distribution, since any attempt to intercept the key will leave a detectable trace allowing mitigating action. qOptica delivers high key rates, has a compact form factor, and is well-suited to free-space implementations for practical deployments.
