A company called Qrypt Inc. will incorporate aÂ quantum random number generator developed by Oak Ridge National Laboratory into existing encryption techniques, strengthening cyber security, a press release said.
Qrypt has exclusively licensed the technology from ORNL, a U.S. Department of Energy laboratory. It’s intended to help defend against cyber attacks, including those posed by quantum computing.
Encryption uses codes or mathematical algorithms to make information such as messages or stored data unintelligible to unauthorized readers.Â Quantum computers make use of the quantum states of electrons or other particles to store and process information as quantum bits.
The press release said Qrypt will incorporate ORNLâ€™s quantum random number generator into the companyâ€™s existing encryption platform. It will use inherent quantum randomness to create unique and unpredictable encryption keys enabling virtually impenetrable communications, the press release said.
“The advent of quantum computing offers a fundamentally new approach to solving some of the worldâ€™s most difficult and pressing problems,” it said. “However, quantum computing will also render current encryption methods obsolete and require a reimagined, quantum-based approach to protecting data.”
â€œThe cryptography we have developed is based on true quantum sources of entropy and is mathematically proven to be unbreakableâ€”even in theory,â€ said Denis Mandich, Qryptâ€™s chief technology officer at the companyâ€™s New York City office.
â€œUntil recently, this class of technology was unavailable at the scale required to encrypt Internet-sized datasets,â€ Mandich said. â€œSimply relying on increasing the complexity of cryptographic algorithms has again proven to be a failing bet.â€
ORNLâ€™s research is integral to Qryptâ€™s hybrid approach: combining quantum physics hardware with post-quantum cryptographic algorithms and software.
â€œWe anticipate a long and productive partnership with one of the nationâ€™s premier labs as we continue to develop secure computing technologies,â€ Mandich said.
One method for successful, failsafe encryption will come from encoding messages with encryption keys that are truly random, the press release said. That is, there is no realistic chance the exact key sequence used could be generated more than once.
To harness quantumâ€™s perfect randomness, ORNL co-inventor Raphael Pooser and his colleagues from the labâ€™s quantum sensing, computing, and communications teams developed a quantum random number generator that detects the presence and characteristics of electro-magnetic waves, called photons, streaming from a light source.
â€œA field of quadrillions of photons are produced and pass through a beam splitter,â€ Pooser said. â€œDifferent from other quantum random number generatorÂ technologies, our method does not require that we wait for a single photon to appear, but allows us to use the collective statistics of large numbers of them.â€
The ORNL device can detect and measure the quantum statistics of photons present in the field and use each one as the basis for creating truly unique encryption keys that are impossible to decipher or predict.
â€œWhile true and quantum random number generators have been available for years, they were impractical to incorporate into server size appliances and their output was always very limited,â€ Mandich said.
ORNLâ€™s scientific achievement can be proven based on quantum entropy, a purely probabilistic effect, he said.
â€œMany competing technologies advertise true randomness and pass modern statistical testing, yet there is no guarantee they do not have a pattern discoverable in the future,â€ Mandich said.
â€œHistorically, patterns, predictability, and repetition are a critical flaw for many crypto systems, allowing them to fall to basic cryptanalysis,â€ he said.
Qrypt will incorporate ORNLâ€™s technology into a suite of quantum-resistant encryption techniques and technologies, including a card or chip enabling quick encryption of vast datasets. Data protected by this technology will be secure against attack by quantum computers or any future computational device and developments in the mathematics of cryptanalysis.
Co-inventors of the ORNL quantum random number generator are Raphael Pooser, Travis Humble, Brian Williams, Bing Qi, and Benjamin Lawrie of the labâ€™s Quantum Information Science group, part of ORNLâ€™s Computational Sciences and Engineering Division.
