News summary:
- In the face of growing cyber threats and the advent of quantum
computing, robust and future-proof network security is
critical
- Joint trial features Adtran’s open DWDM system combined with
QKD key exchange and Adva Network Security quantum-safe
encryption
- Demo uses hybrid key exchange, blending classical, approved
cryptography with Toshiba’s QKD for ultimate Layer 1 security
Adtran today announced its collaboration with Orange on a lab
trial of quantum key distribution (QKD) technology, marking a key
step towards safeguarding real-world networks from the threat of
quantum computer attacks. Using a unique arrangement of the most
advanced QKD and WDM technologies, the milestone multi-vendor demo
successfully showcased 400Gbit/s transmission of a QKD-secured
100Gbit/s data stream over a 184km SSMF through three QKD links and
two trusted nodes. A hybrid approach combining classical
cryptography and QKD was utilized, setting a new standard for
future-proof security. Running over heterogeneous end-to-end
infrastructure, the trial demonstrates the technology’s maturity
for widespread commercial deployment. Both the Layer 1 encryption
and hybrid key exchange used in the trial are enabled by Adva
Network Security’s ConnectGuard™ solution.

“As we navigate the opportunities and challenges that quantum
computing presents, it’s clear we’re at the beginning of a new era
in network security. Our successful lab trial with Adtran
highlights the magnitude of industry collaboration required to
harness the full potential of quantum technology and secure our
digital future,” said Gilles Bourdon, VP of wireline networks and
infrastructure at Orange. “The synergy between Adtran’s FSP 3000
open optical transport technology, Adva Network Security’s
ConnectGuard™ encryption, Toshiba’s latest QKD systems, and our
expertise in network integration sets a formidable benchmark for
quantum-resistant communications across Europe.”
The trial featured Adtran’s FSP 3000 with OpenFabric™️
technology for efficient encryption key distribution and optimized
link performance. Leveraging a coherent 400Gbit/s DP-16QAM channel,
the platform transported a QKD-secured data stream across two
trusted nodes and three links, spanning 184km of standard,
single-mode dark fiber. One of the trial’s key achievements was
overcoming data loss and distance constraints while transporting
significant volumes of quantum-secure data alongside the quantum
channel. The trial introduced a hybrid key exchange, blending
classical asymmetric methods with QKD, creating a robust dual layer
of security. While classical key exchange ensures immediate data
protection in line with current cryptographic standards and
governmental approval, QKD offers future-proof security, resilient
against future computational advancements. The details of the trial
will be presented in Glasgow, UK, at ECOC 2023.
“By utilizing a QKD trusted-node configuration provided by our
technical partner Toshiba Europe/Japan, we’re showcasing some of
the practical applicability of this technology in today’s networks.
At Adtran, we’ve always been at the forefront of quantum security
advancements, consistently applying the latest developments in QKD
and post-quantum cryptography. This trial further underscores our
dedication to pushing boundaries in this field,” commented
Christoph Glingener, CTO of Adtran. “We’ve also always been
committed to championing interoperability, promoting and
contributing to open standards, such as the ETSI interface for QKD
key delivery. Our latest collaboration with Orange emphasizes that
an open, cooperative approach in the design and implementation of
QKD solutions is indispensable to propel this vital technology at
the speed we all require. Together, we’re setting the stage for a
future where our data remains secure, irrespective of the
challenges coming over the horizon.”
