Session will reveal how optical networks can leverage post-quantum cryptography to protect against current and future threats
- Speakers: Helmut Grießer, director of advanced technology at Adva Network Security
- Topics: Solution: Post-quantum cryptography
- When: Thursday, October 16, 4:20 p.m. CEST
- Where: seQUcom 2025 – Securing Enterprise Communications – From Quantum Risk to Resilience, Union Halle, Frankfurt, Germany https://sequcom.de/#about
Quantum computing is moving from theory to reality, creating an urgent challenge for today’s encryption standards like RSA and ECC. As these algorithms face obsolescence, organizations must prepare for a secure transition. Post-quantum cryptography (PQC) is emerging as the cornerstone of future-proof networks, with global standardization efforts led by NIST and guidance from national security agencies such as Germany’s BSI. Regulatory frameworks and transition roadmaps from the EU and other authorities are shaping how enterprises can achieve quantum resilience.
In this session, Helmut Griesser will explain how post-quantum cryptography can be practically implemented in optical transport systems and why crypto-agile architectures are essential for a smooth and secure migration path. Drawing on Adva Network Security’s real-world experience, the presentation combines technical insight with a vendor-neutral perspective, highlighting integration strategies, transition planning, and regulatory considerations. Attendees will gain clear guidance on how to prepare their networks for quantum resilience, today and in the years ahead.
