Quantum computers pose a significant threat to current cryptographic systems, with the potential to crack widely used key exchange methods and put sensitive data at risk. While quantum technology doesn’t yet have the power to mount a successful attack, adversaries can store encrypted communications today and decrypt them at a later date, once quantum computing capabilities advance. 

In this presentation, Tobias Fehenberger will describe two basic methods for quantum-safe key exchange. Post-quantum cryptography (PQC) uses new algorithms designed to withstand even the power of quantum computers. Quantum key distribution (QKD), meanwhile, relies on the physical properties of quantum bits to reliably detect an attack on security mechanisms. Tobias will explain the distinct advantages of each approach and show how combining them can ensure long-term data protection. Practical examples will illustrate real-world benefits, and specific recommendations will be provided for the migration of existing systems.
