ZTNA - Fundamentals

Zero Trust Network Access (ZTNA) is a raising architectural model for company networks that brings answers to the challenges of our time (cloud access, secure hybrid cloud, edge & personal devices, mergers & acquisitions, widescale supply chain & ransomware attacks). And while a transformation was already on its way the pandemic put additional pressure on IT departments around the globe, enforcing a new openness, that otherwise might have been delayed for a few additional years.

Post-Quantum Cryptography Series

As a community of cryptography experts and researchers in Worldline and as part and contributors of the NIST post-quantum cryptography standardization competition , we would be happy to share with you our experience, expertise and thoughts in cryptography and post-quantum cryptography (PQC) in an accessible way. Our intention is to publish a series of articles on various topics related to cryptography & PQC and to get you in touch with fresh news (concepts, key principles, standards, challenges, solutions.)

What's quantum cryptography?

A quantum introduction

Quantum physic is getting discovered during the 20th century and is made of multiple theories that seem to solve current classical physic problems. Actually, it is so important that where quantum laws applies, Newton’s don’t. And vice versa. It describes two worlds where physics laws are just not the same. And this is why it radically changes the cryptography concept. We do not use commons physics laws but we use quantum one’s. And as we will see, these new rules allow us to be faster and stronger.
