Sigrun Goluch: homomorphic cryptography. Gentry’s privacy homomorphism

Sigrun Goluch: The development of homomorphic cryptography From RSA to Gentry’s privacy homomorphism

Ever since the discovery of public-key cryptography by Diffie and Hellman in 1976, the necessity for total privacy of digital data has become stronger and stronger, especially since the internet has become an indispensable part of both our private and work lives. Naturally, the question for more secure encryption schemes arose in the past few decades.
One way to achieve con?dentiality in applications, such as online banking, electronic voting, virtual networks etc. are
homomorphic and especially fully homomorphic cryptographic schemes. Fully homomorphic cryptosystems or privacy homomorphisms were introduced by Rivest, Adleman, and Dertouzous in 1978. They asked for a way to allow a third, untrusted party to carry out extensive computation on encrypted data, without having to decrypt fi?rst. The search for fully homomorphic cryptosystems began and ended almost 4 decades later when Craih Gentry published his fully homomorphic method. Although not yet useful for practical applications, it ended the long search for the in 1978 emerged question about the existence of privacy homomorphisms.

Victory at the iCTF 2011

The team of the Technical University of Vienna “We_0wn_Y0u” could achieve victory at the iCTF 2011 under the direction of Adrian Dabrowski. In a very exciting, nine-hour competition against 85 international competing teams, also Martin Mulazzani, Peter Frühwirt and Manuel Leithner put, as representatives of SBA Research, their skills regarding attacks and defenses of IT infrastructure to the test.

With a broad international participation field (i.a. US, Russia and China), iCTF is one of the the largest Capture-the-Flag contests worldwide. Foto

Guest Talk: Kai Zhang, Large Scale Unsupervised and Semi-Supervised Learning

Kai Zhang (Lawrence Berkeley National Laboratory, US Department of Energy),

Topic: Matrix approximation.

Nov 28, 3pm, SBA

Title: Large Scale Unsupervised and Semi-Supervised Learning

Abstract

Clustering is a fundamental data explorative step in pattern recognition and machine learning. This talk involves two types of clustering paradigms, the mixture models and graph-based clustering methods, with the primary focus on how to improve the scaling behavior of related algorithms for large-scale application. The first part is on simplifying mixture models, and the second part is on applying low-rank matrix approximation with novel sampling scheme in a large family of mainstream learning algorithms. Topics on community detection and large scale supervised learning (SVM) will also be included.

Wer klaut hier meine Daten: TU Forum

Internetsicherheit, Hacker und Datenschutz

Der weltweite freie Datenverkehr hat auch seine Schattenseiten: Unbekümmerte Internetuser gehen viel zu unvorsichtig mit ihren Daten um, wichtige Webseiten weisen oft ernste Schwachstellen auf, Hacker finden immer wieder neue Methoden, in Computersysteme einzudringen. Edgar Weippl (Institut für Softwaretechnik und Interaktive Systeme, TU Wien, sba-research), Christian Platzer und Gilbert Wondracek (Seclab, Institut für Rechnergestützte Automation, TU Wien) werden mögliche Gefahren aufzeigen, über Methoden von Hackern erzählen und gemeinsam diskutieren, ob es überhaupt jemals ein „sicheres“ Internet geben kann.

Guest talk: A Bird’s-Eye View of Optimal Codes and Symmetric Cryptography from Combinatorial Designs

A Bird’s-Eye View of Optimal Codes and Symmetric Cryptography from Combinatorial Designs

Dimitris E. Simos, Department of Mathematics, National Technical University of Athens,

 Abstract: In the past few decades, combinatorial design theory has grown to encompass a wider variety of investigations, many of which are not apparently motivated by any practical application. Rather, they are motivated by a desire to obtain a coherent and powerful theory of existence and properties of designs. Nevertheless, it comes as no surprise that applications in coding theory and communications continue to arise, and also that designs have found applications in new areas. Cryptography in particular has provided a new source of applications of designs in computer science, and simultaneously a field of new and challenging problems in design theory.

In this lecture, we present a number of applications of combinatorial designs in which the connection with classes of optimal codes and modern symmetric (private-key) cryptography appears to be substantial and meaningful. In the first part, we present some new results for self-dual codes and quasi-cyclic codes and exemplify some of their advantages in terms of encoding and decoding. In the continuum, we survey recent powerful private-key cryptosystems from special classes of combinatorial designs, that posses beautiful combinatorial properties. Practical aspects of the cryptosystems, in terms of security and cryptanalysis are analyzed and examples of real-time encryption and decryption are provided using cryptographic algorithms. We conclude, by providing a state-of-the-art comparison of private-key block ciphers in the field of modern cryptography.
