Collaboration Award 2015

The CROSSING Collaboration Award

The CROSSING Collaboration Award is presented for excellent internal collaborative work and outstanding progress in research collaborations within CROSSING, for which all members of the CRC are eligible. It is awarded annually by the CROSSING directorate. Eligible for the Award is any collaboration between projects, for example joint publications, contributions to CogniCrypt, joint software tools or demonstrators or joint bachelor or master thesis.

Winners of the Collaboration Award get a trophy and certificate, and each collaborator receives funds for conference or workshop participation (travel, accommodation, conference fee), freely selectable by the price winners.

The learning with errors problem (LWE) is one of the most important problems in lattice-based cryptography. The goal of the LWE challenge is to determine the practical hardness of LWE, to gain an overview of the best known LWE solvers, and to motivate additional research eff?ort in this direction. The team has set up a web page that presents the LWE challenge to the community. At this page, all instances can be downloaded. Furthermore, solutions can be submitted and correct solutions will be displayed in a hall of fame.

The LWE challenge is not only a collaboration between CROSSING projects P1 (Florian Göpfert, Juliane Krämer) and S5 (Niklas Büscher) but also with international partners – University of California, San Diego (UCSD), University of Tartu and TU Eindhoven – and an industry partner, Cybernetica.
