Cryptography in a Modern 5G Call: A Step-by-Step Breakdown
Modern telecommunications networks rely on multiple layers of cryptography at every step of a call or data session. Understanding the complexity of the process and the amount of cryptography involved is critical for post-quantum migration planning - an initiative some of my advanced telecommunications clients are kicking off these days. And many are widely underestimating how much cryptography is used. From the moment a user’s…

Next-Generation QKD Protocols: A Cybersecurity Perspective
Traditional QKD implementations have demonstrated provably secure key exchange, but they come with practical limitations. To address these limitations, researchers have developed next-generation QKD protocols. These advanced protocols improve security by reducing trust assumptions and mitigating device vulnerabilities, and they enhance performance (key rate, distance) through novel techniques. The article includes a high-level overview of the most notable next-gen QKD protocols.

Adiabatic Quantum Computing (AQC) and Impact on Cyber
Adiabatic Quantum Computing (AQC), and its variant Quantum Annealing, are another model for quantum computation. It's a specialized subset of quantum computing focused on solving optimization problems by finding the minimum (or maximum) of a given function over a set of possible solutions. For problems that can be presented as optimization problems, such as 3-SAT problem, quantum database search problem, and yes, the factoring problem…

CRQC Readiness Index Proposal
This proposal outlines a composite, vendor‑neutral “CRQC Readiness” indicator. It intentionally avoids one‑number vanity metrics (like only counting qubits) and instead triangulates from three ingredients that actually matter for breaking today’s crypto: usable (logical) qubits, error‑tolerant algorithm depth, and sustained error‑corrected operations per second.
