The increase in “deep fakes”, fraud, and cybercrime is threatening trust in the sincerity of the transactions that enable society to run on a daily basis, as well as in innovation and technical progress. The certification of data and transactions therefore remains essential, and cryptography meets this requirement. Its keys protect messages, thus guaranteeing the […]

Orange and the quantum technologies for the security of data exchange
Quantum Physics: from everyday life applications to network security The word “quantum” relates to the world of the infinitely small, therefore the constituent elements of matter (molecules, atoms, particles, etc.). The objects around us respect the laws of classical physics for space and time: for example, if a car is traveling from point A to […]

Quantum computing is breaking down the barriers of cryptography
When postulating that the number of transistors on a chip would double every year, cofounder of Intel Gordon Moore predicted that the industry would reach a physical limit around 2020, that of the size of atoms. Quantum physics, which studies atom behaviour, is being called upon to extend “Moore’s law”. Applied to computing, the quantum […]

KeeeX, the startup that enables document certification
How did your startup, KeeeX, come to be? Originally, the idea was to turn any type of document into an “augmented” file via technical metadata and proofs of integrity, identity and date, a file whose cryptographic fingerprint could be anchored, or not, in the blockchain. Our added value lies in the fact that the proofs […]

Experimenting quantum key exchange over the Côte d’Azur
Orange is involved in the University of Côte d’Azur’s Quantum@UCA project on quantum cryptographic key exchange over a city network.

The PIN is dead, long live the PIN! Thanks to Artificial Intelligence (AI), your phone is now able to recognise your handwriting. A new mobile app developed by a team of researchers from Rennes, France [1] will allow you to log in by writing on your smartphone. Replacing the famous virtual keyboard used for typing […]

Sébastien Canard, a cryptographer who is good for you
In the early 2000s, Sébastien Canard is offered a thesis at Orange. His supervisor is none other than the eminent Marc Girault, expert in cryptography who manages the R&D of the group: “Marc Girault is a bit like my mentor. He taught me cryptography and I often had the opportunity to work with him. “After […]

Jean-Jacques Schwartzmann builds your profile, using your smartphone
“I genuinely consider myself to be an official member of France Telecom”, he said with a grin. Jean-Jacques Schwartzmann joined Orange Labs Caen in 1988. At that time, it was a SEPT (Joint Research Department of La Poste and France Telecom), and it was there that he entered into the game. “I started working on […]
