Important notice about SecAppDev 2020

Due to the current situation with COVID-19 (Corona), with deep regret, we feel bound to postpone SecAppDev 2020 indefinitely. While there have been no official instructions to postpone events such as ours or reduce travel, both attendees and speakers have informed us that they are unable to attend SecAppDev.

We hope everyone in SecAppDev stays healthy, and wish everyone the best for the coming months.

SecAppDev 2020 Lecture Details

Quantum computers, quantum crypto, and postquantum crypto

Bart Preneel
Wednesday March 11, 14:00 - 15:30
Short description

Quantum computers are in their infancy, but they are expected to have a major impact on computing. This session will focus on the impact of quantum technologies on cryptography and secure communications.


Quantum computers have been conceived in the early 1980s. Today, IBM has built a quantum computer with 53 qubits, while Google has 72 qubits and D-Wave Systems 5000 (but with weaker properties). In the fall of 2019, Google has claimed quantum supremacy by performing a previously infeasible computation.

This session will explore the principles behind quantum computers and discuss their potential applications. Cryptographers have been investing heavily in identifying new algorithms to achieve post-quantum cryptography. Physicists believe that they can harness quantum physics to create “unbreakable” Quantum Key Distribution. This session will assess the potential of these technologies.

Key takeaway

How to prepare for the migration towards post-quantum cryptography.

Public Key Infrastructure (PKI) fundamentals

Lecture by Bart Preneel

PKIs ensure the secure delivery and management of public keys. One example is the ecosystem supporting HTTPS, but PKIs are also used in payment systems (EMV) or intranets. This session covers how to manage keys, certificates, and revocation.

The never-ending crypto wars

Lecture by Bart Preneel

Law enforcement agencies complain that encryption impedes their work, hence they keep asking for bans, backdoors or access to keys. Many others argue that weakening encryption would undermine legitimate security interests of citizens and society. Is there a right decision and will this debate ever end?
