We’re proud to present the first-ever end-to-end, line-rate optical fiber link using post-quantum cryptography (PQC), implemented with Data Processing Units (DPUs) and demonstrated at 92.3 Gbps!
In a hybrid PQC setup using Kyber and Dilithium, we’ve shown that full-stack quantum-resistant encryption can:
✅ Achieve near-baseline throughput
✅ Slash CPU load by 60% via DPU offloading
✅ Operate over 240 km of optical fiber using 400ZR+ coherent modules
✅ Integrate seamlessly into modern edge/cloud/HPC data centers
🔁 Our novel approach offloads all crypto operations—authentication, key exchange, encryption—to DPUs, freeing the server CPU and enabling truly scalable quantum-safe networks.
🧠 Hybrid PQC + AES tunnels.
📡 240 km link.
⚙️ Hardware-accelerated.
💡 Ready for real-world deployment.
📊 Performance Results:
🔽 Left: Throughput vs PQ Tunnel Configs
🔽 Right: CPU Usage (Server vs DPU)
