Abstract

Building trust in the context of the digital world in one of the most important, yet elusive goals. Manifestations of trust management systems are ubiquitous in digital interactions, ranging from the authentication of people and websites (e.g. X.509 certificate system), assessing the reputation of sellers in online marketplaces, or assessing the trustworthiness of devices. On the other hand, Blockchain technology, as introduced with Bitcoin in 2008 has opened a lot of interesting possibilities in the path towards decentralized and secure trust management systems. This talk will provide a short introduction on Blockchains and then explore the field of applying Blockchain-based constructs in trust management for cryptographic authentication.
