Nov 21, 09.00-12.00 @ SBA Software security is becoming increasingly important due to numerous emerging threats exploiting software vulnerabilities. This course begins with a broad overview of various software security threats and some of the most effective countermeasures used to thwart them. More specifically, software practitioners will learn how to… Read More
The awareness of information security and IT compliance has increased considerably in the recent past. SBA Research takes this into account and expands its range of services. On 14/11/2013, we welcomed about 50 interested partners at the event “SBA lädt ein – Secure Your Business” and introduced our new department… Read More
Cryptography for the Next Generation Cloud, Daniel Slamanig, Graz University of Technology, 8010 Graz, Austria As is common practice in research, many new cryptographic techniques have been developed to tackle either a theoretical question orforeseeing a soon to become reality application. Cloud computing is one of these new areas, where new… Read More
New Privacy-Preserving Proxy-Type Signature Schemes, Christian Hanser, Graz University of Technology, 8010 Graz, Austria In this talk, we present two new proxy type signature schemes, which, in contrast to conventional proxy signature schemes, hide the delegated message space from outsiders. In short, proxy signature schemes allow an originator to delegate signing rights for messages out of… Read More

Nov 12, 1pm @SBA The lecture focuses on the potential of Chebyshev polynomials for privacy-enhancing techniques in data mining. Two protocols are considered: 1) The calculation of the arithmetic mean according to Kiltz, Leander and Malone-Lee (2005). 2) The secure distributed learning of decision trees according to Lindell and Pinkas… Read More
Together with sipgate and ISMK Stralsund, Gabriel Gegenhuber, researcher at SBA Research and University of Vienna, and Michael Pucher, researcher at SBA research, discovered and investigated a vulnerability in the Voice of LTE (VoLTE) stack that is broadly used within MediaTek-based smartphones. ∞
In the Mediatek modem, there is a possible system crash due to a missing bounds check. This could lead to remote denial of service, if a UE has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation. ∞
