The Fraunhofer Institute for Photonic Microsystems IPMS has developed a new key management system (KMS) specifically designed for use in quantum-secure networks. The system enables the secure exchange of secret keys and ensures reliable, secure data distribution across large-scale network infrastructures.
In view of the computing power of future quantum computers, traditional methods of key distribution, such as RSA and Diffie-Hellman, are under increasing pressure. To mitigate this risk and ensure secure digital communication, Fraunhofer IPMS's KMS software employs quantum key distribution (QKD) technology, which is rooted in quantum principles. This enables individual point-to-point connections to be linked into a scalable and secure network, allowing cryptographic keys to be distributed symmetrically and in a controlled manner across multiple nodes and domains. As a result, an additional end-to-end security and communication layer is created for critical infrastructures. QKD not only enables secure key exchange, but also detects any eavesdropping attempts, ensuring that interference is immediately reported to the relevant parties. Integrating QKD into a cybersecurity strategy therefore provides the highest possible level of protection against emerging quantum threats.
Special features of the Fraunhofer IPMS Key Management System (KMS)
Fraunhofer IPMS is a reliable partner for companies that require quantum-secure communication. With its many years of expertise, innovative technologies and cutting-edge research in quantum key distribution (QKD), the institute helps companies to safely overcome the challenges of quantum computing and to build networks that will stand the test of time. “Our key management system is at the heart of complex QKD networks,” explains Dr Alexander Noack from Fraunhofer IPMS. “It coordinates key requests, generates physically secure keys, reliably distributes them, and manages their lifecycle.” Centralized control via a modern, container-based architecture enables transparent, flexible and efficient management of even large networks. Thanks to its high scalability, the platform can be used in research and demonstration environments, as well as in large, multi-node networks.
Fraunhofer IPMS is setting an important milestone for secure communication in the future with its system, which complies with the ETSI-GS-QKD-014 standard. High-performance quantum random sources ensure the highest security standards, and a QKD-encrypted communication layer secures key exchange, even over public networks.
Fraunhofer IPMS is currently developing an inter-domain interface via shared trusted nodes to enable the future networking of multiple QKD domains. This will enable seamless interoperability and network expansion.
Possible applications and benefits
The KMS developed by Fraunhofer IPMS extends quantum key distribution from simple point-to-point links to full network infrastructures. This enables a wide range of sectors to benefit, including telecommunications and metro networks, critical infrastructure such as energy, transport and healthcare, data centers and cloud providers, government and research networks, as well as Industry 4.0 environments. Companies and public authorities can thus secure multiple sites simultaneously, without the need to install dedicated point-to-point connections for each individual link.
“We have already successfully demonstrated the performance of our system in the QuNET+MOBIXHAP project, which explored various scenarios ranging from simple laboratory networks to complex topologies. In addition, our inter-domain interface, currently under development, will enable secure communication across domain boundaries and provide investment security for ‘Q Day’,” explains Dr Noack.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
