Towards Backward-Compatible Post-Quantum Certificate Authentication

We have blogged about post-quantum cryptography before. Quantum computers would pose a threat to PKI algorithms and systems that we know today. Cisco, with our academic collaborators, has been focusing on quantum-resistant hash-based signatures for a few years now with LMS and SPHINCS+ and more. NIS…

Cybersecurity in the Post-Quantum Era

One of the great scientific challenges of our time is the construction of a practical quantum computer. Operating using the counterintuitive principles of quantum physics, such a device could rapidly explore an vast number of possible states. It could perform computational tasks that are far beyond…
