Kayaks & Dreadnoughts

Kayaks & Dreadnoughts in a sea of crypto

Workshop on secure communications and computation for very small and very big IT systems.

The event took place on the 15th and 16th of September 2016 at Brussels, Belgium, at Université Libre de Bruxelles (ULB). This workshop targets people interested in cryptography and security, more precisely in following areas:

  • Secure implementations of crypto in small and constrained environments such as smart cards, car keys and microcontrollers.
  • Security of large IT infrastructures such as data-centers and cloud computing platforms.
  • Protocols that small and large IT systems use in order to “talk” to each other in a secure way


We will talk about following topics

  • Side-Channel Attacks and hardware implementations of cryptographic algorithms in constrained devices
  • Homomorphic encryption and its applications such as cloud computing
  • Key management and White-box cryptography
  • Ways that can be used to analyze protocols as well as protocols used in practice such as OpenSSL and SSH.


A kayak is a very small boat that is generally propelled using a double-bladed paddle.

A dreadnought is a type of heavy steam turbine propulsion battleship that is equipped with very heavy-calibre guns.

The workshop will take place at the Solbosch Campus of ULB at building A, door Y, auditorium “AY2.108“.

You can find several hotel options around the area near the campus (most of them are in about 10 minutes walking distance).

Some hotels have blocked several rooms for our guests till the middle of August.

If you want to use Warwick hotel you can send them the form that they provided to us.

If you want to have a lower rate at Hotel Brussels you can send an e-mail to with a mention “Workshop Securité” (you’ll get 99 euro for a Single room or 109 euro for a double room, it includes breakfast). Prices at the hotel fluctuate daily depending on multiple factors, so you should check all options.

You can get to Brussels:

  • By train as well as by TGV Thalys, if you are coming from another country the train will get you to Bruxelles-Midi a.k.a. Brussel-Zuid a.k.a. Gare Du Midi a.k.a Zuidstation. Yes.. we have French and Dutch at the same time, so any name might be written in one or the other language (or both) depending on where you are, we hope you will not be lost in Belgium!
  • By plane, the two nearest airports are Zaventem (just outside Brussels) and Charleroi (a couple or hours away, but it welcomes the cheap-flights airlines)

How to get to ULB when you are already in Brussels or at least in Belgium:


Registrations are closed!

Registration for PhD students, postdoctoral researchers, professors and researchers from academic institutions are free but mandatory. Registration fee for other participants is 150 euros.
