Mapping the Supply Chain: A Faster Path to Organizational Resilience

In this episode of Shielded, Jo Lintzen speaks to Sarah McCarthy, Quantum Readiness Program Lead at Citi, who shares how Citi's quantum readiness program has evolved since 2022. They discuss supply chain readiness, and why the first step toward quantum safety does not require a dedicated team or advanced algorithms.

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.

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.
