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
Processes specify how personal and business data are dealt with in information systems. Traditionally, process control in this context means prevention, i.e. ensure processes’ adherence to security and privacy policies. In contexts where process flexibility and changes happen, preventive approaches become no longer practicable. This talk argues that in order… Read More
