Quantum Readiness for Mission-Critical Communications (MCC)
Mission-critical communications (MCC) networks are the specialized communication systems used by “blue light” emergency and disaster response services (police, fire, EMS), military units, utilities, and other critical operators to relay vital information when lives or infrastructure are at stake. These networks prioritize reliability, availability, and resilience – they must remain operational even during disasters or infrastructure outages. For example, in a hurricane that knocks out…

Harvest Now, Decrypt Later (HNDL) Risk
"Harvest Now, Decrypt Later" (HNDL), also known as "Store Now, Decrypt Later" (SNDL), is a concerning risk where adversaries collect encrypted data with the intent to decrypt it once quantum computing becomes capable of breaking current encryption methods. This is the quantum computing's ticking time bomb, with potential implications for every encrypted byte of data currently considered secure.

Post-Quantum Cryptography PQC Challenges
The transition to post-quantum cryptography is a complex, multi-faceted process that requires careful planning, significant investment, and a proactive, adaptable approach. By addressing these challenges head-on and preparing for the dynamic cryptographic landscape of the future, organizations can achieve crypto-agility and secure their digital assets against the emerging quantum threat.

Quantum Era Demands Changes to ALL Enterprise Systems
In my work with various clients, I frequently encounter a significant misunderstanding about the scope of preparations required to become quantum ready. Many assume that the transition to a post-quantum world will be straightforward, involving only minor patches to a few systems or simple upgrades to hardware security modules (HSMs). Unfortunately, this is a dangerous misconception. Preparing for this seismic shift is far more complex…

Bills of Materials for Quantum Readiness: SBOM, CBOM, and Beyond
Quantum computing threat is forcing organizations to inventory their digital assets like never before. With powerful quantum attacks on the horizon, businesses must identify what they have - software, cryptography, sensitive data, hardware - before they can secure it. Security standards and government directives now urge a comprehensive cryptographic inventory as the first step toward quantum readiness. In practice, compiling these inventories is daunting. Modern…

Inside NIST’s PQC: Kyber, Dilithium, and SPHINCS+
In 2022, after a multi-year evaluation, NIST selected CRYSTALS-Kyber, CRYSTALS-Dilithium, and SPHINCS+ as the first algorithms for standardization in public-key encryption (key encapsulation) and digital signatures. Kyber is an encryption/key-establishment scheme (a Key Encapsulation Mechanism, KEM) based on lattice problems, while Dilithium (also lattice-based) and SPHINCS+ (hash-based) are digital signature schemes.

The Future of Digital Signatures in a Post-Quantum World
The world of digital signatures is at an inflection point. We’re moving from the familiar terrain of RSA and ECC into the new territory of lattices and hashes. It’s an exciting time for cryptography, and a critical time for security practitioners. Authentication, integrity, and non-repudiation are security properties we must preserve at all costs, even in the face of revolutionary computing technologies. With careful preparation,…

Cryptographically Relevant Quantum Computers (CRQCs)
Cryptographically Relevant Quantum Computers (CRQCs) represent a seismic shift on the horizon of cybersecurity. In this article, we’ve seen that CRQCs are defined by their ability to execute quantum algorithms (like Shor’s and Grover’s) at a scale that breaks the cryptographic primitives we rely on daily. While still likely years (if not a decade or more) away, their eventual arrival is not a question of…
