Cisco Integrates Chip-Based QKD Tech into Routing Infrastructure

Cisco Systems and KETS Quantum Security have collaborated to integrate KETS' chip-based Quantum Key Distribution (QKD) technology with Cisco's IOS XR routing infrastructure. This integration aims to provide automated key exchange and encryption across existing Ethernet-based networks.

The joint demonstration showed seamless interoperability between KETS' QKD system and Cisco routers, enabling automatic key exchange and encryption without disrupting network performance. The result is a scalable architecture capable of protecting sensitive data across metropolitan and wide-area networks.

The integrated solution combines KETS' QKD with Cisco routers using MACsec to provide end-to-end encryption that increases quantum resilience and is operationally compatible with existing network infrastructure. Key benefits of the integrated solution include increased quantum resistance, compatibility with existing Ethernet-based networks, reduced hardware footprint through chip-scale QKD, and automated, continuous key refresh for enhanced security.

Cisco was an early supporter of hardware QKD, with support in IOS XR routers beginning with version 7.9.1 in 2023. KETS and Cisco plan to continue their partnership, exploring expanded use cases and integration of KETS hardware within Cisco's ecosystem.
