Quantum-Secure Networks: Protect Your Data from Quantum Decrypt Threats

Classical encryption is failing. Discover how end-to-end quantum-safe encryption and crypto-agility safeguard your communications, devices, and cloud infrastructure today.

Quantum-secure networks protect communications and identities even if quantum computers break classical encryption. They combine quantum-secure encryption methods, strong key management, and end-to-end protection - from devices and applications to the cloud. Because attackers are capturing data today to decrypt it tomorrow, migrating now is critical.

Risks to network communications in the quantum era:

Attacks on key exchange: man-in-the-middle attacks during handshakes, compromised certificate and supply chains
Weak key management: insecure generation/storage, long key lifetimes, lack of rotation and automation.
Harvest-now, decrypt-later: data intercepted today decrypted later with quantum computers.
Break of RSA/ECC: forged certificates/signatures, identity theft, tampered connections.
Outdated protocols and lack of crypto agility: rigid systems (e.g., legacy TLS/IPsec/IoT stacks) hinder rapid algorithm changes.

Quantum-Safe Communication Infrastructure: How a central Quantum Key Management System (KMS) securely buffers and distributes quantum-generated keys to end-user domains over classical and quantum channels.

End-to-End Quantum-Secure Networks: Anchored in Physics, Built for the Future

Protect communications today and in the quantum era with information-theoretic security, automated KMS key lifecycles, and certified QRNG randomness.

Quantum-secure networks protect communications and identities with end-to-end quantum-secure encryption and robust key management. This keeps data safe - today and in the quantum era.

Quantum secure networks:

Anchor security in physics
Resist store-now, decrypt-later attacks
Generates and exchanges keys with information-theoretic security through Quantum Key Distribution (QKD)
Manages key lifecycle, buffers/distributes quantum generated key in Key Management System (KMS)
Supplies certified true randomness (QRNG) for seeds, keys, and nonces

Industrial-Grade QKD & QRNG Solutions by Fraunhofer IPMS

Harnessing quantum physics to deliver unbreakable data protection and true hardware-based randomness for high-security applications.

Quantum Key Distribution (QKD)

Quantum Key Distribution is one of the most promising technologies for next-generation cybersecurity architectures. It enables the absolutely secure exchange of encryption keys based on the laws of quantum physics – any attempt to intercept the communication can be detected immediately, as it alters the quantum system.

The Fraunhofer IPMS possesses extensive expertise in photonic integration, quantum optics, and secure communication systems. Building on this foundation, the institute develops scalable and practical QKD systems that can be integrated into industrial environments, critical infrastructures, and future quantum communication networks.

We offer:

Development of QKD components and modules
Integration of photonic systems into existing communication networks
Joint research on standardization and interoperability
Participation in national and European funding initiatives (e.g., Quantum Flagship, IPCEI, BMBF programs)

Quantum Random Number Generation (QRNG)

Quantum Random Number Generation exploits the inherent unpredictability of quantum mechanical processes to produce true randomness – a foundation for secure encryption, authentication, and simulations.

The Fraunhofer IPMS develops hardware-based QRNG solutions using integrated photonic technologies. These systems offer the highest level of trustworthiness and are optimized for use in security-critical applications ranging from cryptography and cloud infrastructures to quantum metrology.

We offer:

Development and validation of QRNG hardware
Integration into communication and sensor systems
Joint research on quantum randomness and signal processing
Test environments for industrial partners and research institutions

Collaboration

Fraunhofer IPMS acts as a bridge between fundamental research, applied development, and industrial implementation. For funding agencies, research institutions, and industry partners, the institute offers:

state-of-the-art infrastructure for photonic and quantum-optical systems,
extensive experience in the management of publicly funded research projects, and
active participation in national and European quantum initiatives.

Together, we shape the future of secure communication – from quantum photons to industrial networks.
