Throughout my career, I’ve specialized in managing emerging tech risks, building and leading innovation labs focused on quantum security, AI security, and cyber-kinetic risks for global corporations, governments, and defense agencies. Groups such as the Internet Engineering Task Force (IETF) are incorporating PQC algorithms into core internet protocols like Transport Layer Security (TLS), and industry organizations are updating application and systems to guard against the threat of quantum computers. In contrast to the threat quantum computing poses to current public-key algorithms, most current symmetric cryptographic algorithms and hash functions are considered to be relatively secure against attacks by quantum computers. If digital signatures can eventually be forged, firmware validation and trusted software updates can become attack surfaces as well.

Whether a quantum computer capable of breaking RSA exists in 2032 or 2042, the migration deadlines are locked in now. These requirements cascade through defense contractors, regulated industries, and any organization connected to government systems. NSA’s CNSA 2.0 requires quantum-resistant algorithms for all new National Security System acquisitions starting January 2027. NIST’s draft IR 8547 deprecates RSA, ECDSA, EdDSA, and Diffie-Hellman for federal systems by 2030 and disallows them entirely by 2035. These are classical algorithms running on the processors, servers, and devices organizations already own.

Organizations need to think now about long-standing data, digital trust, and the time required to migrate complex environments in a phased, manageable way. PQC is no longer a future challenge – it’s a federal cybersecurity priority that requires action today. This is the layer that answers «Trust Now, Forge Later», where the risk is a forged firmware update signature rather than decrypted data. This paper will help you to better understand and navigate the process as you prepare for post-quantum cryptography, with an emphasis on network infrastructure. With NIST’s post-quantum cryptography standard released, organizations must start preparing to secure essential data against post-quantum threats.

Hybrid cryptographic coexistence

Read on for some answers to common questions about this developing technology and NIST’s efforts. NIST is leading a global effort to create electronic defenses against such attacks through its Post-Quantum Cryptography (PQC) project, which released the first three finalized PQC standards in 2024. IT experts can find technical resources on our PQC standards page.Additional information on transitioning to the new standards is available on our NCCoE Migration to PQC page.

Symmetric key quantum resistance

PQC does not require quantum computers or any specialized quantum hardware. Lattice-based cryptography, the foundation for NIST’s primary standards, uses the difficulty of finding short vectors in high-dimensional mathematical lattices. PQC algorithms achieve quantum resistance by relying on mathematical problems believed to be hard for both classical and quantum computers. Unlike quantum cryptography, which uses quantum physics to protect information, PQC is implemented entirely in software and runs on existing classical hardware.

This guidance supports the transition to PQC and includes hardware and software categories with example types of widely available products that protect sensitive information. Although quantum computing technology capable of breaking modern public-key encryption does not yet exist, government agencies and critical infrastructure entities—including both public and private sector organizations—must begin https://scale-models.net/the-risks-of-collecting-what-you-need-to-know/ preparing now. Once quantum computers become sufficiently powerful, they will be able to break many of today’s widely used encryption and digital signature algorithms—the cryptographic methods that currently protect the confidentiality and integrity of data and support essential network security functions.

In some cases, cryptographic processing can be offloaded to hardware to reduce CPU overhead while maintaining stronger protection. Harvest Now, Decrypt Later refers to the risk that adversaries capture encrypted data today with the expectation of decrypting it once quantum computers mature. The risk is not limited to the arrival of a future quantum computers that can break encryption.

It initially focuses on key exchange algorithms but by now includes several signature schemes. Both the Ring-LWE key exchange and supersingular isogeny Diffie–Hellman (SIDH) key exchange can support forward secrecy in one exchange with the other party. It is clear that symmetric-key systems offer the smallest key sizes for post-quantum cryptography.citation needed To transmit an encrypted key to a device that possesses the symmetric key necessary to decrypt that key requires roughly 256 bits as well.

These standards aim to provide solutions for different situations, employ varied approaches for encryption, and offer more than one algorithm for each kind of application in the event one proves vulnerable. Additional algorithms still under consideration are designed for general encryption and do not use structured lattices or hash functions in their approaches. To stave off attacks by a quantum computer — if and when a cryptographically relevant one is built — the worldwide community must retire current encryption algorithms. Instead of billions of years, it’s possible a quantum computer could solve this puzzle in days or even hours, putting everything from state secrets to bank account information at risk. Conventional cryptographic algorithms select two very large prime numbers — which are only divisible by 1 and themselves — and multiply them to obtain an even larger number. However, advanced quantum computers remain a strong possibility, and they would have such a major impact on present-day encryption that the world must prepare for them.

Why Current Cryptography Will Break

Its security rests entirely on hash functions, making it the safest bet against future cryptanalytic surprises, at the cost of signatures up to roughly 50 KB depending on the parameter set. ML-DSA (Module-Lattice-Based Digital Signature Algorithm, FIPS 204, formerly CRYSTALS-Dilithium) is the primary standard for digital signatures, replacing RSA and ECDSA in code signing, certificate https://www.montsec.info/zero-party-data-the-structural-reset-of-privacy-and-personalization/ issuance, and authentication. It replaces RSA and ECDH in TLS handshakes and similar key agreement protocols, and is the algorithm most organizations will deploy first. NIST’s post-quantum standardization process began in 2016 with 82 submissions.
