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

Cryptographic algorithms

Bart Preneel
Monday March 9, 11:00 - 12:30
Short description

In this session, you will learn about various cryptographic building blocks and their security properties. With that knowledge, you can select the right algorithm for the challenge you are facing.


The cryptographic algorithm zoo includes stream ciphers, block ciphers, hash functions, MAC algorithms, authenticated encryption schemes, public key encryption, and digital signature schemes. Each of these algorithms has different security properties and serves a specific purpose. A good understanding of these algorithms is essential.

In this session, we investigate these cryptograhpic building blocks, what they can and cannot do for you, and how to use them correctly. In the end, you will be able to select the right algorithm for the challenges you're trying to solve. In essence, you will be able to find your way in the algorithm zoo.

Key takeaway

Understanding different types of cryptographic algorithms, and the security properties they provide.

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?
