The biggest risk to PQC migration is you (and other humans)

What if the biggest threat to your cybersecurity strategy isn’t quantum computing, but humans? In this episode of Shielded, we welcome Professor Bill Buchanan, OBE, FRSE, a global leader in applied cryptography, digital trust, and secure system design.

The Crypto Agility Paradox: When Hardware Becomes Your Security Bottleneck

In this episode of Shielded, we are joined by Cassie Crossley, Vice President of Supply Chain Security in the Global Cybersecurity & Product Security Office at Schneider Electric. Cassie shares the hard-earned lessons from a multi-year crypto agility program in one of the world’s largest OT environments.

Your Hardware Refresh Is a Quantum Deadline with Mamta Gupta, Lattice Semiconductor

In this episode of Shielded, Johannes Lintzen sits down with Mamta Gupta of Lattice Semiconductor to explore how hardware-rooted security must evolve to meet the post-quantum challenge.

A Tight Security Proof for SPHINCS+, Formally Verified

In this work, we formally prove a tight security bound for SPHINCS+ using the EasyCrypt proof assistant, establishing greater confidence in the general security of the scheme and that of the parameter sets considered for standardization.

Group signatures and more from isogenies and lattices: generic, simple, and efficient

We construct an efficient dynamic group signature (or more generally an accountable ring signature) from isogeny and lattice assumptions.

The Cost of Maintaining Keys in Dynamic Groups with Applications to Multicast Encryption and Group Messaging

In this work we prove lower bounds on the (communication) cost of maintaining a shared key among a dynamic group of users. Being "dynamic'' means one can add and remove users from the group.

Tighter Adaptive IBEs and VRFs: Revisiting Waters’ Artificial Abort

In this paper, we analyze proofs based on the partitioning technique through a new lens.

Open-source or commercial PQC libraries: How do I choose?

In this video, Ben Packman, PQShield's Chief Strategy Officer talks with our Senior Product Manager, Michele Sartori about some of the key differences between open-source and closed-source solutions for post-quantum cryptography.

Post-quantum cryptography and secure boot

In this video, Axel Y Poschmann, PQShield's VP of Product and Ben Packman, Chief Strategy Officer discuss some of the current issues around deploying post-quantum secure boot.

PQShield: at the heart of the PQC conversation

Team PQShield includes some incredible people. We're the largest collaboration of commercially-based post-quantum cryptographers anywhere in the world.

Quantum Security For Automotive

The next generation of cybersecurity threats has become a concern within the automotive sector, particularly when it comes to the power of quantum computers.

The Financial Market’s Transition to Post-Quantum Cryptography

This whitepaper, in conjunction with Quant-X, summarizes the current state of the PQC standards and the governmental regulations, outlines generic financial market specific threats that can be mitigated by post-quantum cryptography.
