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

Public Key Infrastructure (PKI) fundamentals

Bart Preneel
Tuesday March 10, 09:00 - 10:30
Short description

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 function of a Public Key Infrastructure (PKI) is to ensure secure delivery and management of public keys. TLS and HTTPS rely on public certificate authorities, but alternative trust models exist as well. In fact, different trust models lead to different key architectures.

In this session, you will discover what is needed to build and deploy a PKI. We investigate common pitfalls with key management, including the often underestimated revocation process. In the end, you will understand how public PKIs work. You will also have a list of requirements and best practices for setting up a private PKI system.

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?
