Quantum Secure Tunneling Protocol: a post-quantum secure tunneling protocol for certificate-authenticated encrypted sessions and VPN-class transport.

BPC — Bound Pair Credentials: pair-authorized, signed, replay-resistant API request protocol

Symmetric Authenticated Tunneling Protocol: a certificate-free secure tunnel protocol using deterministic key hierarchies, cost-based authentication, and authenticated encryption.

Secure Infrastructure Access Protocol: a certificate-free two-factor access protocol using removable token state, passphrase unlocking, and one-time key lifecycles.

Quantum Secure Messaging Protocol Simplex: a post-quantum one-way secure messaging protocol for authenticated encrypted sessions with replay resistance and transcript-bound key establishment.

Archival residue layer for RET parallel conditions. Preserves referable resonance residues, replay resistance, and anti-restoration semantics as a minimal authority pack.

Quantum Secure Messaging Protocol Duplex: a post-quantum bidirectional messaging protocol for authenticated encrypted sessions with replay resistance and transcript-bound key establishment.
