Architectural Layers & Silicon Defenses

Layer 1: Optical Physical Layer & MACsec Silicon (IEEE 802.1AE MACsec / 100GBASE-LR4): Encrypting every Ethernet frame at Layer-2 with zero frame expansion or packet fragmentation.
Layer 2: Line-Rate Cryptographic ASIC Pipeline (Pipelined AES-256-GCM / GHASH Multiplier): Processing multi-hundred gigabit network streams with deterministic latency bounded under 250 nanoseconds.
Layer 3: Post-Quantum Tunnel Negotiation Core (IKEv2 (RFC 7296) / WireGuard / ML-KEM-768): Negotiating ephemeral tunnel keys combining classical ECDH with post-quantum lattice key encapsulation.
Layer 4: SD-WAN Overlay & Multi-Cloud Fabric (BGP EVPN / VXLAN Encrypted Overlays): Establishing dynamic mesh tunnels connecting AWS, Azure, Google Cloud, and on-premise enterprise datacenters.

Cryptographic Telemetry & Compliance: 100-800G (Line-Rate Throughput Capacity) | < 250 ns (Layer-2 Encryption Latency) | Hitless (Zero-Packet-Loss Re-Keying) | Quantum-Safe (Hybrid ML-KEM Key Exchange)

Hardware Roots of Trust for Trans-Continental Data Backbones

Cross-datacenter traffic and wide area networks traverse public internet infrastructures, dark fiber spans, and leased carrier circuits exposed to optical tapping and nation-state interception. WanHSM delivers line-rate hardware encryption capable of securing 100 Gbps to 800 Gbps backbone links with sub-microsecond transit latency, utilizing post-quantum hybrid key exchange.
