AegisWire™ · Secure Transport

Transport Architecture,
In Production

AegisWire runs a purpose-built secure transport layer. Not a protocol wrapper. A platform with its own session model, wire discipline, and operational trust story — designed from first principles for enterprise security requirements.

Hybrid post-quantum key exchange
Stream-scoped PCS
Session migration & roaming
Packet-level metadata privacy

Session & Mobility

Transport properties implemented and enforced across all deployment modes. No aspirational features listed as current capabilities.

UDP-Multiplexed Sessions with Stream-Scoped PCS

Multiple isolated data streams over a single UDP connection. Independent flow control and stream-scoped post-compromise security boundaries — no cross-stream contamination.

CID-Based Roaming & Multipath

Connection-ID-based continuity survives network changes without reconnection. Supports concurrent paths with per-path crypto isolation. Handles mobile transitions, Wi-Fi/cellular handoff, and connectivity interruptions without session teardown.

Anti-Replay Protection

Replay attack prevention at the protocol level. Every packet carries replay-resistant state. Duplicate and out-of-window packets are rejected.

Deterministic Wire Discipline

Predictable state transitions, bounded message sizes, strict validation rules. The protocol behaves identically under review and in production — no hidden state.

Anti-Amplification Controls

Anti-amplification enforced in both the handshake and data plane. The transport rejects unauthenticated traffic that could be used for amplification attacks. Connection establishment requires proof of origin before resource commitment.

UDP-Based Transport

Purpose-built on UDP with its own session model, loss recovery, ACK, and congestion control (BBR-family or CUBIC). Not a tunnelled TCP stack. Designed for low-latency, high-throughput enterprise workloads with real mobility support.

Security Properties in Operation

All of the following are implemented and enforced across all deployment modes.

Hybrid Post-Quantum Key Exchange
Classical + post-quantum hybrid construction, aligned with NSA CNSA 2.0 algorithm guidance and UK NCSC post-quantum migration guidance. Both classical and post-quantum threat models are addressed simultaneously at session establishment. Protects today's traffic against future quantum decryption.
Stream-Scoped Post-Compromise Security
Stream-scoped forward-secure key evolution with a bounded healing window. Session keys evolve automatically — a compromised key limits exposure to material derived before the compromise. Blast radius is bounded at the stream level.
Packet-Level Metadata Privacy
Header protection prevents metadata exposure at the wire level. Early-session privacy matters because exposure during setup and routing happens before a session is fully established.
Privacy-Safe Observability
Operational observability uses metadata signals, not content inspection. Full operational visibility without any access to payload content or session material.
Signed Policy Distribution
Trust-anchor rotation and revocation without service interruption. Gateway-level enforcement of signed policy artefacts. Device enrollment binding with policy-aware session acceptance.
Private Handshake with Metadata Privacy
Mutually authenticated handshake with metadata privacy from the first packet. Session keys derive through a layered key schedule into stream-scoped forward-secure keys. Long sessions use continuous post-quantum refresh for hardening.

Privacy & Observability Boundaries

Payload encryption alone does not solve the whole problem. Early-session privacy matters because exposure during setup and routing happens before a session is fully established — before higher-level controls apply.

AegisWire treats metadata during connection setup as part of the security problem, not an afterthought. Most transport stories mention post-quantum algorithms or session resilience in isolation. AegisWire positions both as part of one coherent long-horizon security architecture.

Packet-level privacy
Header protection prevents metadata exposure at the wire level — not just payload encryption.
Stream-scoped PCS
Post-compromise security is stream-scoped, limiting blast radius of any key compromise.
Post-quantum key establishment
Hybrid key exchange protects sessions against future quantum decryption — today's traffic, tomorrow's threat model.
Metadata-only telemetry
Operational observability uses metadata signals — no content inspection, no payload access.
Why PQ + PCS Together

PQ transition readiness addresses future decryption of today's traffic. PCS addresses security posture after a hypothetical key compromise during active operation. Both matter. AegisWire implements both as one coherent security architecture — not separate feature checkboxes.

1
Initial Packet Sent
Zero pre-sent payload — handshake is private from the first packet
2
PQ Key Exchange
Hybrid post-quantum construction established (CNSA 2.0 aligned)
3
Trust Anchor Checked
Device and gateway identity verified against signed trust anchor
4
Policy Enforced
Signed policy artefact applied — default-deny posture active
5
Session Secured
Stream-multiplexed, PCS-active, metadata-private session established
6
PCS Running
Stream-scoped forward-secure key evolution — continuous post-compromise recovery

Security Claims

AegisWire's transport layer is designed around six formal security claims, each enforced at the protocol level.

SC-1
Session Confidentiality
All session data is encrypted with keys derived from authenticated handshake. No cleartext payload on the wire after session establishment.
SC-2
Session Integrity
Tampered packets are detected and rejected. Authenticated encryption ensures data integrity across every frame.
SC-3
Mutual Authentication
Both endpoints authenticate during the handshake. No unauthenticated party can participate in an established session.
SC-4
Forward Secrecy
Compromise of long-term keys does not compromise past session keys. Ephemeral key exchange provides forward secrecy for every session.
SC-5
Post-Compromise Security
Stream-scoped forward-secure key evolution limits exposure after key compromise. The bounded healing window ensures recovery within a deterministic number of operations.
SC-6
Metadata Privacy
Header protection and sealed handshake prevent metadata exposure from the first packet. Connection identifiers are not linkable across migrations.
