Today’s Internet cannot do without confidentiality and online identification. The cryptography typically used to achieve this, however, is under threat from quantum computers. While a practical quantum computer is years away, it also takes years to standardise and deploy alternative cryptography. Worse, applications that store data long‐term (e.g., captured encrypted Internet traffic) require action now, since if current cryptography is broken, stored data is immediately compromised.

Cryptographers are developing post‐quantum cryptography (PQC) that is secure against attacks with quantum computers. While much progress has been made developing and trialling algorithms, we lack a complete view of the problem space. More boldly: we cannot answer the question “what if the whole Internet had to switch to PQC?”. Nobody “owns the Internet” so who will tackle this challenge? Sure, the tech giants should take action, but the Internet is much broader than that. In my view, this challenge can only be solved with an independent holistic approach that considers all aspects of the Internet.

In this talk I will explore the research challenges for quantum-proofing the whole Internet and will propose a research agenda to tackle these challenges. I will show how we need to examine all parts of the Internet that rely on public-key cryptography and how we need to decide if we can simply replace algorithms, if we maybe have to re-engineer protocols and applications, or if the costs are simply too high and we should retire protocols or applications.

Watch the trailer here.

Roland van Rijswijk-Deij

After two decades in the industry, working on applied cryptography and network security, Roland is professor of measurement-based Internet security at the University of Twente since 2021. His research interests are in the application of global-scale Internet measurements to support empirically-backed securityanalysis and improvements of Internet protocols and the transition of the Internet to post-quantum cryptography.

University of Twente, NLnet Labs, Netherlands

Roland is a member of the Design and Analysis of Communications Systems group at the University of Twente, and a researcher in the Twente University Centre for Cybersecurity Research (TUCCR). Roland also advises NLnet Labs, a not-for-profit that develops open source software for core Internet protocols, on scientific research.

The Cyber CNI Lecture Series is a free monthly event that typically takes place on the last Wednesday of the month from 2pm to 3h30pm CET.

The event consists of a 45-minute expert presentation followed by a 45-minute discussion.

The Cyber CNI Speaker series aims to raise awareness and understanding of cyber security issues among all audiences. It aims to enable an ongoing dialogue between experts from industry and academia and the general public (citizens, families, small and large businesses, public organizations, etc.). All of us are concerned.

The events are broadcast live on Youtube ( and LinkedIn, allowing worldwide remote participation – including a tool to participate in the discussion.

How the digital transformation is changing our lives

The COVID-19 pandemic has shown all of us the benefits of information technology. It allows us to work at a distance, to live at a distance, and most importantly, to keep in touch at a distance – with younger and older people, those closest to us, and even make new contacts.

Our society relies more and more on information and operational technologies. Examples include water, energy, heat and cooling supply, communications, healthcare, production and processing of goods, transportation, national security, banking, research and education, and food production.

What all these areas have in common is that they make intensive use of networked distributed computer systems. These systems can be attacked in many ways. This is no longer just a problem for computer “pros” because computer systems are essential to all of us. The effects of “cyber-attacks” range from power outages to the collapse of the health care or banking sectors.
