Scaling Post-Quantum Tunnel Ingress to 100 Gbps via eBPF, XDP, and kTLS

Core engineering and protocols for Line-Rate Hardware Offload.

Eliminating Cryptographic CPU Bottlenecks at Edge Scale

Terminating tens of thousands of simultaneous post-quantum TLS handshakes per second can exhaust CPU resources if implemented naively. MLKEMSecure decouples the handshake phase from the data transfer phase: while the initial ML-KEM key exchange runs in high-performance vectorized user-space, established symmetric session keys are immediately passed to Linux kTLS.

Integration with SmartNICs and DPDK

For enterprise backbone providers and hyperscalers, we integrate with DPDK and SmartNIC acceleration engines. The network card hardware performs line-rate packet decryption and DMA transfers directly into application memory buffers, maintaining 100 Gbps line-rate throughput with minimal CPU overhead.
