Collaboration Award 2018

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.

Sensitive digital data, such as health information or governmental archives, are often stored for decades or centuries. The processing of such data calls for long-term security. Secure channels on the Internet require robust key establishment methods. Currently used key distribution protocols are either vulnerable to future attacks based on Shor's algorithm, or vulnerable in principle due to their reliance on computational problems. Quantum-based key distribution protocols are information-theoretically secure and offer long-term security. However, significant obstacles to their real-world use remain. This paper, which results from a multidisciplinary project involving computer scientists and physicists, systematizes knowledge about obstacles to and strategies for the realization of long-term secure Internet communication from quantum-based key distribution. We discuss performance and security particulars, consider the specific challenges arising from multi-user network settings, and identify key challenges for actual deployment.
