Collective Authorities – Transparency and Decentralized Trust at Scale

Collective Authorities – Transparency and Decentralized Trust at Scale

Talk given at https://www.dotsecurity.io/.

Abstract
The secret keys of critical network authorities–such as time, name, certificate, and software update services–represent high-value targets for hackers, criminals, and spy agencies wishing to use these keys secretly to compromise other hosts. In this talk, we present the concept of collective authorities (cothorities) which enable to decentralize authoritative systems thereby strengthening the overall robustness of such systems and providing a proactive approach to transparency that can either replace or complement existing (centralized) methodologies. Our talk also highlights various applications of cothorities to areas like software updates, distributed randomness, and cryptocurrencies.
