New innovation consortium sets out to secure Danish share of a rapidly growing technology market by developing next generation's ultra-secure cryptographic systems rooted in quantum physics.
Quantum physics has an air of exoticness and its relevance for our daily lives is likely obscure to most people. Nonetheless, Nature's most subtle phenomena are about to enter society at a vital level, providing information security in future communication and data storage infrastructures with the strength to resist even attacks from full-blown quantum computers.
Quantum communication is a Danish research stronghold. To capitalize on this and foster a new high-tech business area, the Innovation Fund Denmark has invested
This task demands state-of-the-art in technology and research and to this end CryptQ brings together leading businesses in cryptographic hardware (
'The increasing global threat from cybercrime will spur a strong demand for security solutions resistant to future computing technologies. Being part of the CryptQ consortium we actively partake in Danish development of globally leading crypto-systems. We expect quantum safe cryptography to be a standard in zero-trust data environments within 5-20 years', says
Securing critical infrastructure and financial data
The CryptQ consortium also includes
'In Danske Bank, we foresee many applicable benefits of the added security quantum key distribution will bring to our infrastructure. Hosting a field test in our datacenters will provide us firsthand experience with the technology. Later on, we hope to see a seamless large-scale implementation in our crypto chain,' says
Quantum randomness is the key to secure encryption
Cryptography works by randomizing information using an encryption key. For symmetric encryption like AES, which is the most widely employed scheme, that very same key undoes the randomization, enabling the receiver to reveal the original information.
Thus, it is of utmost importance for the security that only the legitimate sender and receiver are in possession of the encryption key. This makes key distribution an absolutely central part of the cryptographic system. It is exactly this challenge the CryptQ consortium sets out to solve using a technique known as 'continuous variable quantum key distribution'.
'CV-QKD allows us to generate and distribute encryption keys though optical fibers and at the same time ensuring that no adversaries have gained information about the key. In CryptQ, we will develop a full-stack cryptographic system based on that principle', says project leader
To understand the unrivaled security offered by the technology we must dive into quantum physics.
'Say, I receive a pulse of light in some, to me, unknown quantum state and try to measure it. The result will be completely unpredictable and as a result I cannot trace back the original state of the pulse. There is a fundamental randomness to Nature at the quantum level,' explains professor
The CryptQ consortium welcomes technology stakeholders to join as associate partners with the opportunity of following the development of the future's quantum secured communication technology.
