As a wholly owned federal company, BWI GmbH is the IT system house of the German Armed Forces. As a link between the military and industry, BWI operates and develops the IT of the German armed forces, carries out digital transformation projects and tests and implements innovative use cases. In the latter area in particular, BWI focuses on the early and application-oriented use of new technologies. BWI’s service portfolio is clearly differentiated from research, as BWI primarily builds on research results and enables their subsequent implementation in practice. To this end, the Competence Center Quantum Enabled Technologies was founded in the Innovation & Technology division of BWI.

The declared goal is to raise awareness of quantum technologies in the BWI and Bundeswehr environment. Market and technology screenings, knowledge transfer from consulting projects and individual trials are used to derive specific recommendations for action for BWI’s service portfolio.

QuantiCor Security GmbH

QuantiCor Security GmbH is a developer of quantum computer-resistant security solutions for IT infrastructures and the Internet of Things (IoT). As a Darmstadt-based expert in post-quantum cryptography, QuantiCor is a reliable IT security partner for companies from all industries. 

It supports and advises medium-sized and large companies in their migration efforts towards a quantum-safe IT infrastructure. It also provides various security solutions based on post-quantum cryptography, for example, to implement future-proof cloud and network applications. This in particular also includes the use of quantum-safe and crypto-agile communication solutions and key management systems. For IoT, resource-efficient security solutions are provided to run on resource-constrained devices for scalable real-time applications. QuantiCor has also developed the first standard (DIN SPEC 91444) for quantum-safe encryption.

Quantum Optics Jena GmbH

Security and sovereignty of information are granted today by complex algorithm-based cryptography. The rise of quantum computing will challenge our state-of-the art, mathematical based encryption technologies. Quantum Optics Jena GmbH develops and delivers quantum key distribution (QKD) systems based on entangle photon sources to taggle quantum challenges with quantum technologies. This allows the implementation of cyber security solutions based on physical laws. Quantum Optics Jena covers the whole process chain from entangled photon sources, quantum state analysers to quantum key-generation and -management systems. We offer solutions for fiber-based networks as well as payloads and sub-systems for future QKD-satellite networks and constellations. We enable a quantum added value to our customers and partners.

Rohde & Schwarz Cybersecurity GmbH

Rohde & Schwarz Cybersecurity GmbH is an established manufacturer of security products, including in the area of network encryption. Rohde & Schwarz Cybersecurity offers network encryption devices, also for higher security and performance requirements, and is therefore intensively involved in making these devices quantum-secure. As part of research projects, a connection to (external) QKD devices was developed so that the QKD devices together with our network encryptors enable a quantum-secure transmission of user data.

The partners’ QKD devices ensure that a key is exchanged securely using quantum mechanisms, while our devices then use this to secure the user data that is actually to be transmitted. In doing so, we also pay attention to the system security of the resulting solution, so that in addition to the aspect of quantum security, classic security aspects of a secure system architecture such as robust implementations, the smallest possible attack surfaces through to aspects of a secure life cycle from production and delivery to commissioning and operation through to disposal to be fulfilled.

Rohde & Schwarz SIT GmbH

Rohde & Schwarz SIT is an industry leading manufacturer of high assurance security solutions for military and government. Typical products are tactical encryption devices, crypto phones and COMSEC solutions for harsh environmental conditions. Besides that we develop cryptographic modules for modern Software Defined Radios and are involved with the crypto modernization of German armed forces. Of course, all these cryptographic solutions have to remain secure even
with the existence of an universal quantum computer.

Within the industrial consortium Quantum Security, Rohde & Schwarz SIT is especially interested in system architecture, protocol design and evaluation/approval of quantum random number generators. We can contribute with long-time experience of red-black separation, electromagnetic emission security and cryptography as well as approval processes on high security levels.
