Participated in NIST LWC Crypto conference and NIST - PQC 2nd round standardization conference (Nov 4-6 & Aug 22-24 2019)
We work closely with ID Quantique and ISARA on Quantum Security.
Secure Communication Advisors
We help you create a connection that keeps your current data secure even if your opponent has/will have a very large quantum computer. The connection is secure against someone copying your traffic...and lets you know if someone is listening in.
Your encrypted data runs on a secure communication layer using Quantum Key Distribution (QKD). There are a few big examples of this (BT in England, QuantumXchange NY/NJ, Chinese Government Beijing to Shanghai, China QKD satellite).
We help you implement quantum random number generation capabilities.

Quantum – a double-edged sword for cryptography
Defence, finance, social networking – communications everywhere rely on cryptographic security. Cryptography involves jumbling up messages according to a code, or key, that has too many combinations for even very powerful computers to try out.
But quantum computers have an advantage. Unlike regular computers, which process information in ‘bits’ of definite ones and zeros, quantum computers process information in ‘qubits’, the states of which remain uncertain until the final calculation.
The result is that a quantum computer can effectively try out many different keys in parallel. Cryptography that would be impenetrable to regular computers could take a quantum computer mere seconds to crack.
Practical quantum computers that can be used to break encryption are expected to be years, if not decades, away. But that should not be of any reassurance: even if a hacker cannot decipher confidential information now, they could save it and simply wait until a quantum computer is available.
‘The problem already exists,’ said Professor Valerio Pruneri of the Institute of Photonic Sciences in Barcelona, Spain, and the coordinator of a quantum security project called CiViQ. ‘A hacker can take what is stored now, and break its key at a later date.’
The answer, says Prof. Pruneri, is another quantum technology. Known as quantum key distribution (QKD), it is a set of rules for encrypting information – known as a cryptography protocol – that is almost impossible to crack, even by quantum computers.
QKD involves two parties sharing a random quantum key, according to which some separate information is encoded. Because in quantum theory it is impossible to observe something without corrupting it, the two parties will know whether someone else has eavesdropped on the key – and therefore whether it is safe, or not, to share their coded information.
Until now, QKD has usually involved specialist technology, such as single-photon detectors and emitters, which are difficult for people outside labs to implement. In the CiViQ project, however, Prof. Pruneri and his team are developing a variant of QKD that works with conventional telecommunications technology.
They have already created prototypes, and performed some field demonstrations. Now, the researchers are working with industry telecoms clients including Telefónica in Spain, Orange in France and Deutsche Telekom in Germany to create systems that work to their respective requirements, with the hope that the first systems could be online within three years.
Prof. Pruneri’s hope is to create highly secure communication systems up to 100 km in size suitable for governmental, finance, medical and other high-risk sectors within cities. It could even be used by everyday consumers, although Prof. Pruneri says that QKD currently reaches shorter distances and lower speed than regular communication.
Like normal cryptography, QKD needs random keys – strings of numbers – to be generated in the first place. The more random these keys are, the greater the security of the system, as there is less chance of the keys being guessed. But the problem is that the numbers generated with traditional methods often aren’t totally random.
Here, quantum mechanics can again come to the rescue. The behaviour of atoms, photons and electrons is believed to be truly random and this can be used as a way of generating numbers that cannot be predicted.
Professor Hugo Zbinden of the University of Geneva in Switzerland said: ‘Quantum random-number generators profit from the intrinsic randomness of quantum physics, whereas classical true random number generators are based on chaotic systems, which are deterministic and, in theory, to some extent predictable.’
'Quantum computers threaten classical cryptography.'

Quantum random-number generators already exist, but to make them more widely applicable Prof. Zbinden and his colleagues working on a project called QRANGE are improving their speed and reliability, as well as reducing their cost. Currently, they are trying to develop prototypes with a ‘high technology readiness level’ – in other words, prototypes that demonstrate that the technology is ripe for use in the real world.
The work is an important step in ensuring that, while being a threat to the security of our current communications, quantum approaches also provide a path to more secure systems.
‘Quantum computers threaten classical cryptography,’ says Prof. Zbinden. ‘Quantum cryptography can be a solution, (but) it needs high-quality random numbers.’

ABN AMRO & QuTech exploring QKD
Toshiba Research Europe Lab (TREL) is providing commercial QKD equipment to Horizon 2020 UK research effort (2019).
The OPENQKD pilot project is aimed at boosting the security of critical applications in the fields of telecommunications, healthcare, electricity supply and government services. Within the OPENQKD project, TREL will adapt its quantum key distribution (QKD) technology to demonstrate use cases for quantum security in networks in several European cities. The OPENQKD project is set to run for three years and will have a budget of €15m. Its consortium consists of 38 partners from 13 EU member states and Horizon 2020 associated states.
