Description Presenter: Ismail Khoffi and Philipp Jovanovic

In this talk we discuss CoSi, a novel protocol for collective signing, which enables authorities to have their statements collectively signed by a diverse, decentralized, and scalable group of (potentially thousands of) witnesses. Furthermore, we show how CoSi can be utilised to proactively harden critical Internet authorities and in particular present applications to Certificate Transparency, DNSSEC, software distribution, the Tor anonymity network, and cryptocurrencies. The collective authorities research project is a joint effort between teams of security researchers from the University of Yale and the Swiss Federal Institute of Technology in Lausanne (EPFL) and is being lead by Prof. Bryan Ford.
