# Cordon Sovereign Communications

> Cordon is a sovereign communications platform utilizing NIST-standard ML-KEM-768 for post-quantum defense. Designed to protect high-stakes enterprise data against Harvest Now, Decrypt Later (HNDL) attacks.

## Core Features
- **Post-Quantum Cryptography**: ML-KEM-768 hybrid encryption.
- **Ghost Protocol**: Double ratcheting for perfect forward secrecy.
- **Zero-PII Metadata**: Ephemeral routing tokens and HMAC blind indices.
- **Data Sovereignty**: Customer-managed WORM archiving across jurisdictions.
- **Hardware-Locked Identity**: Cryptographic attestation tied to device secure enclaves.

## Architecture
Cordon operates on a zero-knowledge relay architecture. The relay server never possesses decryption keys and cannot reconstruct the social graph of its users. All sessions are authenticated using hardware-backed cryptographic keys.
