The mission of the laboratory is three-fold:

• to carry out fundamental and applied research in cryptography and systems security;

• to teach cryptography and systems security in the context of undergraduate and graduate university courses, as well as in the context of industrial training programs;

• to participate in R&D projects and to provide consulting services without compromising the general academic objectives

The head of the laboratory is Prof. István VAJDA. The laboratory was formerly known as E-biz Lab. The laboratory belongs to the Department of Telecommunications at the Budapest University of Technology and Economics.

New MSc special: Security of Communication Systems The Department of Telecommunications launches its new MSc special program on Security of Communication Systems in the spring semester of the 2008/09 academic year. Within this special program, students will study modern communication systems and networks in general, with a special emphasis on their security aspects.Accordingly, our CrySyS laboratory plays a determining role in this special. More specifically, we teach 4 courses, and we supervise laboratory exercises, as well as student semester and diploma projects. More information about the special is available on the web page of the program: http://www.crysys.hu/netsec/. The descriptions of the currently proposed semeter projects can be found on the following page: http://www.crysys.hu/semesterprj.html.

Kick-off meeting of the EU funded WSAN4CIP project The kick-off meeting of the WSAN4CIP (Wireless Sensor and Actuator Networks for Critical Infrastructure Protection) project takes place on January 19-21, 2009, in Frankfurt (Oder), Germany. WSAN4CIP receives funding from the EU in the context of FP7. In this project, Prof. Levente Buttyan leads the Dependable Networking work package, and several other people from the lab are also involved. The lab is represented by Gergely Acs, Boldizsar Bencsath and Levente Buttyan at the Frankfurt meeting.

Levente Buttyan gives an invited talk in the Heidelberg lab of NEC Europe Levente Buttyan gives an invited talk at NEC Europe, Heidelberg, on Securing Coding Based Distributed Storage in Wireless Sensor Networks on December 19, 2008. The presentation is based on joint work with Istvan Vajda and Laszlo Czap.

Successful completion of the EU funded UbiSec&Sens R&D project The EU funded UbiSec&Sens project, in which several people from the CrySyS Lab participated, was successfully completed at the end of 2008. The final review of the project took place on December 17-18, 2008, in Heidelberg, Germany, here the lab was represented by Prof. Levente Buttyán. A press release appeared on this occasion in TMCnet.com. Our activity in the field of sensor network security will now continue in the EU funded WSAN4CIP project, which starts in January 2009.
