Bernhard Garn and Dimitris Simos from SBA’s MaTRIS research group (https://matris.sba-research.org/) join the 6th Symposium and Bootcamp on the Science of Security (HotSoS) (https://cps-vo.org/group/hotsos), April 2-3 in Nashville, Tennessee.
Bernhard and Dimitris also present their paper ‘Browser Fingerprinting using Combinatorial Sequence Testing’ (Bernhard Garn (SBA Research), Dimitris E. Simos (SBA Research), Stefan Zauner (FH Campus Wien), Rick Kuhn (NIST) and Raghu Kacker (NIST)) (https://cps-vo.org/node/59890), reporting on the applicability of combinatorial sequence testing methods to the problem of fingerprinting browsers based on their behavior during a TLS handshake.
HoTSoS is a research event centered on the Science of Security, which aims to address the fundamental problems of security in a principled manner and is sponsored by the NSA in cooperation with ACM SIGSAC.
Edgar Weippl gives a talk at the Workshop: Autonomous and Remotely Operated Systems: Benefits and Challenges to Nuclear Security hosted by WINS (World Insitute for Nuclear Security) on April 3, 2019.

Last weekend SBA hosted the CTF Team “We_0wn_Y0u” (https://w0y.at) for another round of iCTF (International Capture the Flag), organized by UCSB. After a bumpy start, they were able to secure the 2nd place in the competition.
Congratulations also to Bushwhackers and [SPbCTF] Kappa, for scoring 1st and 3rd place respectively.
W0Y is mainly organized by lecturers and students from the security courses held by SBA Research at TU Wien, and is always open for interested students to join.
Rethink Cybersecurity (hosted by SBA and Anovis) took place on March 14, 2019 as a co event of the 2019 Vienna Cyber Security Week. The session brought together over one hundred decision makers in business, research and government. The agenda featured a total of eight talks and panels on future security threats in cyberspace and new ways of approaching upcoming challenges. On this note SBA introduced five European IT startups targeting respective issues and trying to come up with new ideas, products and services. The selected startups will be competing for the fifth Security Rockstars title.
Alexei Zamyatin has a talk on “Decentralized Mining Pools: Security and Attacks” accepted at the Breaking Bitcoin Conference. The 2019 conference takes place in Amsterdam, from 8-9 June.
You are cordially invited to join Ulrich Habock´s talk on Friday, March 15, 4:00 pm @ SBA Research.
Title: Anonymous Credentials for the Cloud, Revisited.
Abstract: In an attribute-based credential (ABC) sys- tem, users obtain a digital certificate on their personal attributes, and can later prove possession of such a cer- tificate in an unlinkable way, thereby selectively disclos- ing chosen attributes to the service provider.
We present a revision of a previous work on ‘encrypted attribute-based credentials’ (EABC) by S. Krenn et al., which mitigates the security weaknesses of the original construction and moreover considers a much wider attack scenario.
This fundamentally modified system be the basis of our upfollowing prototype, and its reference integration into the web-based OpenID Connect identity layer.
