Awareness to Action: The Blueprint for Quantum-Resilient Security | Garfield Jones

In this episode of Shielded: The Last Line of Cyber Defense, host Johannes Lintzen sits down with Dr. Garfield Jones from CISA to dive into the practical steps for post-quantum migration, making the case that waiting until 2035 is far too late.

Your Cryptography is stuck in 2010 – How to Catch Up | Hart Montgomery

In this episode of Shielded: we speak with Hart Montgomery, Technical Director at LF Decentralized Trust, about how outdated cryptographic dependencies, hidden vulnerabilities, and poor crypto agility are putting critical systems at risk.

How to Build Your 12-Month Post-Quantum Strategy With NIST’s Dustin Moody

Shielded welcomes Dustin Moody, the mathematician leading NIST's post-quantum cryptography standardization project, for an in-depth discussion on why organizations must act now.

Quantum Computing Threat: NIST PQC standards are here… how can you keep ahead?

Cryptographic agility and a clear roadmap to the NIST standards are key to a smooth and secure transition to PQC.

Quantum Computing Threat: An Overview of Post-Quantum Cryptography

The goal of this document is to provide the reader with an understanding of the key technical ideas used in post‐quantum cryptography.

Quantum Computing Threat: The First NIST Post-Quantum Cryptographic Standards

In 2016, the National Institute of Standards and Technology (NIST) launched a open and world‐ wide effort to propose, analyze and eventually standardize post‐quantum cryptographic schemes. In this white paper we find out more.

Scalable Ciphertext Compression Techniques for Post-quantum KEMs and Their Applications

A multi-recipient key encapsulation mechanism, or mKEM, provides a scalable solution to securely communicating to a large group.

The design of scalar AES Instruction Set Extensions for RISC-V

We survey the state-of-the-art industrial and academic ISEs for AES, implement and evaluate five different ISEs, one of which is novel.

Building a Modern TRNG: An Entropy Source Interface for RISC-V

The currently proposed RISC-V True Random Number Generator (TRNG) architecture breaks with previous ISA TRNG practice by splitting the Entropy Source (ES) component away from cryptographic PRNGs into a separate interface, and in its use of polling. We describe the interface, its use in cryptography, and offer additional discussion, background, and rationale for various aspects of it.

ModFalcon: Compact Signatures Based On Module-NTRU Lattices

We introduce a new family of signature schemes based on the falcon design, which relies on module lattices. Our concrete instantiation enjoys the compactness and efficiency of falcon, and allows an intermediate security level.

Cryptographic Divergences: New Techniques and New Applications

In the recent years, some security proofs in cryptography have known significant improvements by replacing the statistical distance with alternative divergences.

Mobile Energy Requirements of the Upcoming NIST Post-Quantum Cryptography Standards

We present an energy requirement analysis based on extensive measurements of PQC candidate algorithms on a Cortex M4 - based reference platform.

Post-Quantum Ciphertext Compression and Applications to Secure Group Messaging

A standard method to establish secure communications between two or more parties is to encrypt a common session key via a key encapsulation mechanism (or KEM).

Secure Update Propagation via Set-Homomorphic Signatures

In this document, we propose to use homomorphic signatures to maintain a consistent database across all nodes of distributed network.

Pyjamask: Block Cipher and Authenticated Encryption with Highly Efficient Masked Implementation

This paper introduces Pyjamask, a new block cipher family and authenticated encryption proposal submitted to the NIST lightweight cryptography standardization process.
