security & cryptography

Authentication, private networking, traffic filtering, and cryptography — the lab's own security tooling, all in development.

κ: In development

### [KeiAuth](https://keilab.io/security/keiauth/)

The lab's own sign-in primitive, designed to need no password and no vendor hardware key. The mechanism is shared under NDA.

⊢: In development

### [kgl-overlay](https://keilab.io/research/kgl/)

Self-hosted, Tailscale-class mesh VPN, built on standard networking and cryptography.

▨: In development

### [KeiWall](https://keilab.io/security/keiwall/)

The lab's own web-application firewall: a Go reverse proxy with signature rules plus small machine-learning models.

⊙: In development

### [MAX crypto](https://keilab.io/security/max-crypto/)

TLS 1.3, Ed25519, ChaCha20-Poly1305, Argon2id and BLAKE2b as C implementations in the MAX runtime, exposed as builtins and gated against RFC test vectors; the SHA-256/Poly1305 hot path is also written as FPGA RTL, verified in simulation.
