A secure communications architecture that defines node trust relationships, policy boundaries, key continuity, audit rules, and interoperability across federated deployments.
Communications architecture
Project CYGNUS DOME
Overview
Post-quantum end-to-end communications architecture for high-trust environments.
Protocol composition for on-premise and cloud deployments, built from FIPS-approved primitives: P-256 ECDH/ECDSA, ML-KEM-768, ML-DSA-65, AES-256-GCM, HKDF-SHA-512, and ledger integrity controls.
An instant messaging app with post-quantum encryption based on the ARKES-Ledger protocol stack, allowing operators to switch between official and private modes from the same interface.
Protocol foundation
ARKES-Ledger
Auditable & Resilient Key Encryption System with Ledger Integrity
ARKES-Ledger is the protocol layer of Cygnus Dome, defining how key establishment, session continuity, and auditable message handling operate across trusted deployments.
Hybrid key establishment uses P-256 ECDH plus ML-KEM-768, with signatures from P-256 ECDSA plus ML-DSA-65.
Symmetric ratcheting is designed to support forward secrecy and post-compromise recovery over time.
Audit paths are tied to ledger integrity so reviewability can exist without collapsing operational control boundaries.
The protocol is intended for on-premise and cloud deployments with controlled policy boundaries, and can be configured for FIPS-approved primitive sets where required.
