One Protocol to
Secure It All.
The encryption protecting your data today will be broken by quantum computers. QuStream makes your existing infrastructure quantum-proof by achieving Operational Perfect Secrecy - faster and more cost-effective than alternatives.
What is QuStream?
QuStream delivers Operational Perfect Secrecy (OPS) at scale - a total generalisation of Shannon's 1949 theorem. Instead of relying on computational hardness, QuStream uses ephemeral Q-Blocks extracted from decentralized quantum noise.
The result? Information-theoretic security (ITS) that bounds adversarial success probability. Intercepted traffic cannot be decrypted - not by quantum computers, and not by any adversary with unbounded resources. QuStream doesn't just resist the quantum era; it mathematically bypasses it.
Peer-Reviewed Research: QuStream's formal OPS framework is published in the IACR ePrint Archive. It establishes the first practical model for non-binary, operational ITS.
Unbreakable Security
Not just quantum-resistant - quantum-proof
Protection that can't be broken even with unlimited computing power. Your data stays secure forever.
200,000x Faster
Always faster than standard encryption
So fast it removes encryption as a bottleneck. Real-time protection without the latency tax. Even AES best-case is 50x slower.
Dramatically Lower Cost
No HSMs. No key infrastructure. No migration debt.
Eliminate expensive hardware security modules, complex key management systems, and constant PQC migration cycles. Drop-in security that pays for itself.
6,400x Faster
Than Post-Quantum Alternatives
QuStream delivers 1 XOR per byte - consistently. No rounds. No polynomial multiplication. Perfect secrecy at the physical limit of the link.
Encryption Latency vs Security
The Complete Picture
How QuStream compares across the metrics that matter to security teams.
| Metric | QuStream | AES + PQC | Traditional AES |
|---|---|---|---|
| Security Level | ∞ Unbreakable Information-theoretic | Computational Hardness assumptions | Vulnerable Quantum-breakable |
| Computing Effort | 1 XOR Per Unit | Polynomial Math High Complexity | 10-14 Rounds Sequential Dependency |
| Quantum-Safe | Forever | Assumed | No |
| Integration Time | Days Drop-in layer | Months | N/A |
| Infrastructure Cost | Lower No HSMs needed | Higher | Moderate |
Still using AES? You're paying for encryption that's up to 6,400x slower than QuStream and vulnerable to quantum harvesting.

Already Here.
A single fault-tolerant quantum computer will retroactively break encryption for 60 billion devices.
Harvest Now, Decrypt Later
State actors are intercepting encrypted traffic today to decrypt it once quantum computers go online.
Universal Infrastructure Collapse
From IoT fleets to military comms, every digital signature securing the modern world becomes forgeable.
Legacy Encryption Failure
RSA, ECDSA, and Elliptic Curve cryptography - the foundation of Bitcoin and Banks - will be broken.
The Timeline to Q-Day
Based on current hardware roadmaps and algorithmic breakthroughs, we're in a race against time.
NIST Standards
First PQC standards released (ML-KEM, ML-DSA, SLH-DSA).
Hardware Scaling
Error-corrected logical qubits become routine in research.
Risk Window
Highest probability of first practical RSA/ECC breaks.
Widespread Risk
Legacy cryptography vulnerable if migration lags.
The Last-Mile Solution
We don't just secure blockchains.
We secure everything.
Solving the "Last Mile" problem through OPS-based embedding within ephemeral Q-Blocks.
HOW IT WORKS
Drop-in security layer - no rip-and-replace required
Last-Mile Delivery
Extending ITS guarantees to endpoints via DFK-guided Q-Block extraction.
Universal Overlay
Deployable on enterprise fiber, satellite, or decentralized Web3 nodes.
C-ITS Secrecy
Achieves OPS through combinatorial ambiguity of decryption candidates.

Adrian Neal, a two-time winner of the NATO Defence Innovation Challenge, is an internationally recognised Cybersecurity & Cryptographics expert, and currently holds the position of Senior Director and Global Lead for Post-Quantum Cryptography at Capgemini.
While primarily advising governments, defence organisations and global multi-nationals on post-quantum readiness, he is also a cybersecurity advisor regarding Central Bank Digital Currencies (CBDC), particularly in respect to the social and economic risks from future post-quantum cryptographic instability.
He is a graduate of Oxford University, from which he received a Masters' Degree in Software Engineering and began his career at IBM in the mid 80's, followed by a decade in the City of London, departing in '98 for Zurich to join UBS Warburg as their first Cryptographics expert while becoming a member of the International Association for Cryptologic Research (IACR).
In almost 40 years, he has held positions in key financial and industrial sectors such as Banking, Insurance, Financial Markets, Energy, Pharma, IT, Aviation and Telecoms, across 8 countries and over 3 continents.
In 2012, he founded the Oxford University spinout Oxford BioChronometrics, developing the most advanced software for detecting fraud in online advertising, winning various blind-tests against ad-industry incumbents, with the research being cited by the Guardian, the Financial Times, the Wall Street Journal and both (US) Houses of Congress, while becoming a winner of the 2017 NATO NCIA Defence Innovation Challenge for Advances in Cybersecurity, and subsequently published in European Cybersecurity Journal.
In 2018, he founded Oxford Scientifica as a research organisation, focused on advanced military communications in low-bandwidth and spectrum-contested environments, becoming a winner of the 2019 NATO NCIA Defence Innovation Challenge for Signal Resilience in the High North.
