Folder: The new paradigm of cryptography

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 confidentiality, authenticity, and integrity of critical communications in particular. This field, which dates back to antiquity, is however undergoing a complete overhaul thanks to the promises of quantum physics.
