ARKA™ QS-Link Quantum-Safe Encryptor
Line-rate Layer 2 / Layer 3 network encryption with post-quantum key exchange and optional QRNG.
Adversaries are recording encrypted traffic today so they can decrypt it once quantum computers mature ("harvest now, decrypt later"). QS-Link encrypts links between data centres, substations, DR sites and offices at line rate, using hybrid key exchange (classical ECDH + NIST ML-KEM) so that intercepted traffic stays confidential well into the quantum era.
An optional quantum random number generator (QRNG) module gives true physical entropy for key generation. It is ready to integrate with QKD networks being built under India's National Quantum Mission.
