Speaker
Description
The National Institute of Standards and Technology (NIST) and the European Union recommend transitioning to quantum-secure cryptography between 2030 and 2035. While Post-Quantum Cryptography (PQC) does not require specialized quantum hardware, it has to withstand the test of time, and it provides only security against quantum computational attacks. Quantum Key Distribution (QKD) offers an alternative approach. Although it requires new network infrastructure, QKD can provide perfect forward secrecy and even information-theoretic security (ITS) when used with a one-time pad. While the broader vision of a quantum internet—including technologies such as quantum teleportation—will require further advances, practical QKD systems are already commercially available.
What will the TNC audience take away from your talk?
The GÉANT community could build its own quantum network, starting with QKD. This would fill the gap between restricted or partially classified QKD networks and academic researchers who need to transfer sensitive data using future-proof encryption. The network could start small and grow gradually. The required technology and algorithms are already available.
