The Quantum Threat
Data stolen today can be decrypted tomorrow.
A cryptographically relevant quantum computer (CRQC) will break the public-key cryptography behind every TLS session, VPN tunnel, code-signing key and secure boot chain. Adversaries are already recording encrypted traffic to decrypt it later: harvest now, decrypt later.
Mosca's inequality: when are you at risk?
x + y > z
- x
- how long your data must stay confidential
- y
- time needed to migrate your systems
- z
- time until a CRQC exists
Grover's algorithm
Weakens symmetric cryptography
- AffectedAES-128, short hashes and MACs
- ImpactEffective security roughly halved; not a practical break
Verdict: strengthen with AES-256 and SHA-384 / SHA-512
Cybersecurity
Security outcomes, not just new algorithms.
Post-quantum cryptography is a means, not the goal. ElvasAI products are built to deliver the core outcomes of a security programme: confidentiality, integrity, authenticity and visibility. They are hardened against today's attackers as well as tomorrow's quantum adversaries.
Confidentiality
Hybrid ML-KEM key establishment with forward secrecy keeps data in transit unreadable, both to attackers now and to anyone decrypting recorded traffic later.
Integrity
Post-quantum signatures on firmware, kernels, modules and updates mean any tampering is detected before code runs.
Authenticity & Identity
ML-DSA certificates and PQ-signed tokens bind devices, services and users to identities that a quantum computer cannot forge.
Zero Trust Enforcement
Every connection is mutually authenticated and every boot is measured and attested, in line with NIST SP 800-207: never trust, always verify.
Detection & SOC Integration
Attestation failures, downgrade attempts, expiring certificates and cryptographic drift are raised as security events for your SIEM and SOAR workflows.
Crypto-Agility & Resilience
Algorithms are swapped by policy when new attacks or standards appear, so cryptographic incidents are handled without re-architecting systems.

Frequently asked questions
Can't find what you're looking for? Our engineers are happy to help.
Ask a QuestionIs the quantum threat real if quantum computers can't break encryption yet?
Yes. Encrypted traffic recorded today can be decrypted once a cryptographically relevant quantum computer exists, so any data that must stay confidential for years is already at risk. Standards bodies have also set firm retirement dates for today's algorithms.
What is the difference between PQC and QKD?
Post-quantum cryptography (PQC) uses new mathematical algorithms that run on existing computers and networks. Quantum key distribution (QKD) uses quantum physics to exchange keys over dedicated optical links. ElvasAI focuses on PQC because it can be deployed in software and firmware across existing infrastructure at scale.
Will post-quantum cryptography slow down my systems?
ML-KEM is computationally very fast, often faster than the elliptic-curve operations it complements. The main differences are larger keys, ciphertexts and signatures. Our products are engineered to manage these sizes, and we measure the real impact in your environment during a pilot.
Why use hybrid cryptography instead of pure post-quantum?
Hybrid modes combine a proven classical algorithm with a post-quantum one, so a connection stays secure as long as either holds. This protects against unforeseen weaknesses in newer algorithms and keeps interoperability with systems that do not yet support PQC.
Do we need to change our applications?
Often not. QVPN protects traffic at the network layer and QGate terminates post-quantum TLS in front of existing APIs, so upstream applications can stay unchanged while their traffic becomes quantum-safe.
Where should we start?
With visibility: you can only migrate cryptography you know about. Our free Quantum Risk Assessment gives a first indication in two minutes.
