Systems & Architecture
Threat models, trust boundaries, and the architecture of systems that stay secure under real-world pressure — not just on the whiteboard.
High Assurance Systems Engineering
Secure design, engineered for certainty.
CE Labs designs and builds systems where security comes first — applied cryptography and rigorous engineering, backed by formal methods where correctness matters most.
Scope of work
$ ce-check ./system/handshake.rs
✓ handshake ⊨ authenticated
✓ key schedule ⊨ forward-secret
✓ primitives ⊨ correct

What we do
Security on every layer.
Protocols & Key Management
Key exchange, authentication, and transport — designed and reviewed against formal security models and the threats they actually face.
Cryptography Engineering
The algorithms at the foundation: implemented for performance and correctness, hardened against side channels, and post-quantum ready.
Machine-Checked Proofs
When the stakes call for it, we go further: machine-checked proofs that the code meets its specification — the strongest assurance there is.
How we work
From Specification to Production.
01 · DESIGN
Design the system
We map the requirements, threats, and trust boundaries up front, then design an architecture that stays secure under the pressure it will actually face.
02 · SPECIFY
Pin down the spec
We capture what the system must do — and what an attacker must never be able to do — as a precise specification that everything else is built and tested against.
03 · IMPLEMENT
Build the system
We build to that spec, with security and correctness designed in from the first line rather than bolted on after, and reviewed as the code is written.
04 · ANALYZE
Confirm it holds
We check the result against the spec through review, testing, and — where the stakes call for it — machine-checked proofs, with every requirement traced to what we specified.
