Große Teile unserer kritischen Infrastruktur wie Stromnetze oder Mobilfunknetze sind sogenannte verteilte Systeme. Sie bestehen aus vielen Rechnern, die in einem Netzwerk zusammen große Aufgaben lösen. Solche Systeme müssen robust sein, möglichst synchron bleiben und eine gewisse Fehlertoleranz aufweisen. „Die meisten verteilten Algorithmen, die dafür eingesetzt werden könnten, sind noch zu langsam, nicht skalierbar und nicht effizient genug, um diese Probleme wirklich zu lösen", erklärt CISPA-Faculty Dr. Julian Loss. Mit seinem Projekt Cryptosystems will er mithilfe modernster kryptografischer Verfahren die Effizienz und Robustheit verteilter Algorithmen deutlich verbessern und so die Netze der Zukunft sicherer und effizienter machen.
