Within Blockchain, Public Key Infrastructure (PKI) is a framework for creating a secure connection between the server and the client in an unsecured network. PKI has long secured the internet but it comes with significant security and resilience challenges and concerns, specifically in the world of web 3.0, the era where we are today. This is when Decentralised Public Key Infrastructure (DPKIs) come into play. The main idea for DPKIs is the ability to establish trust relations between all parties, in a web-of-trust model, avoiding centralized authorities and related root-of-trust certificates. It utilises a consensus algorithm operated over many different machines and replicated by many different entities in a decentralised (blockchain) network, improving operational efficiency, resilience and above all, the security of critical infrastructure across the globe. This webinar brings to the table the latest research and standardisation steps in DPKI that are being put in place by European experts in making Europe a global leader in blockchain-based / decentralised digital identity, bringing a positive impact across different fields, namely on cybersecurity, Identity management and access control.
