Quantum Communication

Quantum Key Distribution (QKD) Post-Quantum Cryptography (PQC)

The new era of encryption

Traditional encryption methods may become vulnerable to quantum computers in the upcoming years. Quantum-secure communication addresses this emerging threat by leveraging innovative next-generation cryptographic techniques designed to withstand quantum attacks.

Quantum Key Distribution (QKD)

QKD is based on fundamental physical principles and leverages quantum mechanical effects to generate cryptographic keys with inherent security. In simple terms, QKD enables the secure exchange of encryption keys, which can then be used for symmetric encryption in applications such as VPNs.

Post-Quantum Cryptography (PQC)

PQC is based on advanced mathematical approaches, such as lattice-based structures. These methods are specifically designed to remain secure even against attacks from quantum computers. The combination of QKD and PQC enables a hybrid encryption approach, delivering a high level of future-proof security for critical communications.

Why Quantum Secure Communication?

Highly Secure Data Transmission

Quantum-resistant connections enable new approaches to highly secure data transmission, particularly in critical infrastructure and the public sector.

Eavesdrop-Proof Communication

Due to fundamental physical principles, unknown quantum states cannot be copied. As a result, any attempt to intercept a key exchange is inherently detectable, effectively preventing undetected eavesdropping.

High Innovative Strength

Quantum technologies lay the foundation for future-proof encryption that remains resilient even against emerging technologies such as quantum computers.
