Cryptography for a
Quantum world
Qausal is our quantum-safe document signing platform powered by ML-DSA-65, plus our Post-Quantum Cryptographic Advisory practice. Integrated offerings that find your most exposed assets and protect them first, starting with the signatures that need to survive the next 50 years.
Every signature you create today is already at risk
Quantum computers will break RSA and ECDSA. Adversaries are harvesting signed documents now, waiting to forge them later.
Harvest Now, Forge Later
Harvest-now-decrypt-later (HNDL) attacks are already documented. Adversaries are collecting signed documents today with the intent to forge or repudiate them once quantum computers arrive. A document signed with classical cryptography has no retroactive protection: you can't upgrade a signature after it's been created.
Regulatory Deadlines
US federal agencies must transition to PQC signatures by 2031. Canada by 2035. The EU's eIDAS 2.0 is aligning. Australia's digital-by-default framework makes this a compliance question.
Documents Must Endure
Property titles need 30+ years of verification. Medical records are lifelong. Financial contracts span decades. Classical signatures won't survive; quantum-safe ones will.
One platform. One practice behind it.
Qausal is where your documents get protected. Advisory is how you know what to protect first, and in what order.
UbQbit Qausal
Upload a document, invite your signers, done. Every signature is ML-DSA-65, and every signed document stays verifiable without us.
- ML-DSA-65 signing, hybrid with ECDSA
- Multi-party signing with a full audit trail
- Portable proof: verifiable offline, no vendor dependency
Advisory & Risk Assessment
Know what to protect first, and in what order. We translate quantum risk into a plan your board and your engineers can both act on.
- Quantum risk briefings for C-suite and boards
- Cryptographic inventory & vulnerability assessment
- PQC migration roadmaps with phased priorities
PQC expertise and direct path from assessment to implementation
Post-quantum cryptography is all we do. That focus means faster results, deeper expertise, and a seamless path from risk assessment to quantum-safe signing.
Weeks, not quarters
- Quantum Risk Briefing delivered in a single half-day session
- Full cryptographic inventory completed in 4-8 weeks
- Migration roadmap in your hands 2-4 weeks after assessment
- No six-month discovery phases or bloated project teams
Assessment to implementation
- Every finding maps directly to a fix, not a slide deck that gathers dust
- Our own quantum-safe signing platform closes the gap we identify
- Crypto-agile architecture means you migrate once, not repeatedly
- Ongoing retainers keep your posture current as standards evolve
Built for your sector
- Deep expertise in legal, financial services, property, and healthcare
- We understand document retention obligations and regulatory timelines
- Risk scoring calibrated to data sensitivity, retention period, and exposure
- Deliverables in business language your board and regulators understand
Built for documents that must endure
We focus on sectors where document integrity is measured in decades, not months.
Legal
Contracts, deeds, and client agreements with 10-25 year retention
Financial Services
Transaction records and contractual obligations spanning decades
Property
Land titles and settlement documents verifiable for 30+ years
Healthcare
Patient records with lifelong sensitivity under privacy law
Government
Federal supply chain entities facing cascading PQC mandates
Built for regulatory reality
Aligned with global PQC transition mandates and digital signature frameworks.
🇺🇸 United States
CNSA 2.0 mandates PQC digital signatures for federal agencies by Dec 2031. Covered contractors face a 2030 deadline.
🇨🇦 Canada
Federal PQC migration plans due April 2026. Critical systems by 2031, full transition by 2035.
🇪🇺 European Union
eIDAS 2.0 and ETSI PQ standards targeting 2026 for planning, 2030 for critical infrastructure, 2035 for full transition.
🇦🇺 Australia
Digital-by-default Electronic Transactions Act, Digital ID Act 2024, and updated AG guidelines make quantum-safe signatures a compliance question.
