SBA at Alpbach – Breakout Session on Cyber-Security

Under the lead of TU Austria, we organize an Alpbach Breakout Session on Cyber-Security as a fundamental right. Participants include Isao Echizen (NII), Lokke Moerel (Tilburg University), Günter Müller (University of Freiburg), Reinhard Posch (TU Graz), Bart Preneel (University of Leuven), A Min Tjoa (TU Wien), and Edgar Weippl (TU Wien, SBA Research).

Mozilla Winter of Security

Klaus Krapfenbauer, one of SBA’s bright students, successfully finished his Winter of Security project at Mozilla.

As part of his master thesis he implemented a PoC for fully automated Let’s Encrypt support in nginx. Due to the design of nginx, this was not a straight forward task. You can read the technical details in the blogpost from Mozilla.

If you are interested in participating in this year’s Winter of Security, please contact Martin Schmiedecker.

Adrian Dabrowski @ the “heise Show”

Adrian Dabrowski talking at the “#heiseshow” about the finale of the Cyber Grand Challenge, the world´s first all-machine hacking tournament, which took place at the DefCon 2016 conference.

SBA at USENIX Security

Members of SBA will be present at USENIX Security and co-located workshops like WOOT or FOCI to cover them for our PRIME partner program. If you run into them, don’t be shy to say hi.


Sebastian and Martin will present two research papers at DFRWS USA, the leading conference in digital forensics.

The first one is on using nano-second timestamps for embedding steganographic information securely, titled “Time is on my side: Steganography in filesystem metadata”. You can find a preprint of the paper, the data and the source codes online. The second paper improves the forensic process by leveraging sub-file hashes part of the Torrent filesharing protocol, “PeekaTorrent: Leveraging P2P Hash Values for Digital Forensics”. Preprint, data and source codes can be found here.

Combinatorial Security Testing Tutorial @ QRS2016

Dimitris Simos (SBA Research), Rick Kuhn (NIST), Jeff Yu Lei (University of Texas at Arlington) and Raghu Kacker (NIST) give a tutorial on Combinatorial Security Testing at QRS 2016.

The tutorial is comprised of two parts focusing on combinatorial testing methods and their usage to security testing.

The abstract can be found here.

Dimitris Simos @ QRS 2016

QRS 2016 takes place from August 1 – 3, 2016 in Vienna, Austria. QRS is organized by University of Texas at Dallas and supported by Graz University of Technology and SBA Research.

SBA at Blackhat & Defcon

Members of SBA will be present at Blackhat and Defcon.

Aaron’s work with Hanno Böck, Philipp Jovanovic and Sean Devlin on nonce re-uses in TLS is scheduled to be presented at Blackhat on August 3rd, 11:30. This work is also nominated for the Pwnie for Best Cryptographic Attack. Adrian Dabrowski will be on-site to cover the presentations for our PRIME partner program.

Meeting of the Bridge Early Phase SPLIT Project

The quarterly meeting of the SPLIT (Security Protocol Interaction Testing in Practice) project took place on July 29th, 2016 at SBA Research. SPLIT is funded under the Bridge Early Phase programme of the Austrian Research Promotion Agency (FFG). The project aims to provide quality assurance of security protocols by combining combinatorial testing and model-based testing methodologies as part of a fully automated test cycle. Recent advances of the project on protocols attacks and certificate testing were discussed.

SBA Research acts as the consortium leader, with Graz University of Technology (Franz Wotawa, Institute for Software Technology), University of Texas at Arlington (Jeff Lei, Department of Computer Science and Engineering) and Objentis Software Integration GmbH (Roland Tscheinig) as project partners. For more information regarding SPLIT see the project’s webpage or contact its project leader, Dimitris Simos at

A summary of the SPLIT project has been featured in a special theme of ERCIM News on cyber security, which can be found here.

Split Meeting

Wilfried Mayer on national TV

Wilfried Mayer was today on national TV and explained Tor, the dark web and how it is used world-wide by dissidents and journalists, not only by perpetrators.

You can watch the segment here for the next few days. Alternatively, you can find it here.

Four papers accepted for the Combinatorial Security Testing Team of SBA Research

The interplay between discrete mathematics and computer science is crucial for the successful deployment of real-world applications but also necessary for the advancement of theoretical approaches and methodologies.  Recently, the combinatorial security testing team of SBA Research has marked significant contributions in this regard:

  • The paper “Algebraic Modelling of Covering Arrays” by Bernhard Garn and Dimitris Simos (both with SBA Research) has been accepted in Springer Proceeding Series in Mathematics and Statistics.
  • The papers “Set-based Algorithms for Combinatorial Test Set Generation” by Ludwig Kampel and Dimitris Simos (both with SBA Research) and “A Combinatorial Approach to Analyzing Cross-Site Scripting (XSS) Vulnerabilities in Web Application Security Testing” by Dimitris Simos (SBA Research), Kristoffer Kleine (SBA Research), Laleh Ghandehari (University of Texas at Arlington), Bernhard Garn (SBA Research) and Jeff Yu Lei (University of Texas at Arlington) have been both accepted for publication at the 28th International Conference on Testing Software and Systems (ICTSS-2016) which takes place on October 17-19 at Graz, Austria.
  • The paper “TLS Cipher Suites Recommendations: A Combinatorial Coverage Measurement Approach” by Dimitris Simos (SBA Research), Kristoffer Kleine (SBA Research), Artemios Voyiatzis (SBA Research), Rick Kuhn (NIST) and Raghu Kacker (NIST) has been accepted for publication at the 2016 IEEE International Conference on Software Quality, Reliability and Security (QRS 2016) which takes place on August 1-3 at Vienna, Austria.

The results of these papers demonstrate the effectiveness of combinatorial methods in security testing together with theoretical advancements on related algorithms for combinatorial testing.
