Quantum-Inspired algorithmic hardening.
Most of the cryptography in use today was designed against classical attackers. We find the algorithms and key material a quantum-era attacker breaks first, and harden them before the threat becomes practical.
Why it matters
Encrypted data intercepted today can be stored and decrypted later, once quantum computers are capable enough. Anything that must stay confidential for years is therefore already exposed to tomorrow's attacker.
Public-key schemes such as RSA, Diffie-Hellman and elliptic-curve cryptography are the ones at risk of being broken outright; symmetric ciphers and hash functions lose part of their security margin. Replacing them across a real system takes years — which is why it starts with knowing exactly what you have.
What we examine
- Cryptographic inventory — every algorithm, key size, protocol and library in use, and where the keys live.
- Quantum exposure — which assets depend on RSA, Diffie-Hellman or elliptic curves, weighed against how long their data must stay secret.
- Post-quantum migration — readiness for the NIST-standardised ML-KEM, ML-DSA and SLH-DSA, including hybrid deployments that combine them with today's schemes.
- Symmetric and hash margins — key and digest sizes measured against quantum search.
- Randomness and key generation — entropy sources, key derivation and nonce handling.
- Implementation hardness — side channels, parameter choices and misuse that weaken a sound algorithm in practice.
- Crypto-agility — how quickly an algorithm can be swapped out when the next one falls.
- Signatures and wallets — signing keys and on-chain signature schemes exposed to quantum attack.
What "quantum-inspired" means here
Quantum algorithm research has produced optimisation and search methods that run on ordinary hardware today. We use them to pressure-test the places where an algorithm's strength is assumed rather than demonstrated, so that hardening decisions rest on measurement instead of on the hope that nobody looks.
What you receive
- A cryptographic inventory, with each item ranked by exposure.
- A migration roadmap ordered by how long the protected data has to stay secret.
- Concrete hardening recommendations: algorithms, parameters and configuration.
- A written report of every finding, with severity, evidence and the fix.
How an engagement runs
- You submit a report describing the system, with any links and files that help us understand it.
- We review it and email you a quotation and a time estimate.
- Once you approve, the audit is carried out against the agreed scope.
- You receive the findings and the guidance to act on them.
No commitment — you receive a quotation before any work begins.
