"Self-Verifiable Decentralized Identifiers and their application to Content Delivery, the IoT, and the Software Supply Chain"

Abstract:  Self-Sovereign Identity (SSI) technologies such as Decentralized Identifiers (DIDs) and Verifiable Credentials enable users to take full control of their identities and information, avoiding reliance on centralized identity providers, thus supporting user privacy. User control and privacy are significant requirements of EU's eIDAS 2.0 framework revision, among other initiatives around the world. In this talk, after reviewing the key features of DIDs and Verifiable Credentials, I will present a new DID method that is compatible with W3C's DID specifications, but does not require a blockchain, a 3rd party registry or any trusted entity. This is achieved by treating the DID's original key pair as the root of trust, thus providing self-verifying properties. Benefits of the proposed scheme include key rotation without having to change the public key/DID, controlled delegation, and document sharing between untrusted entities. Finally, we present applications to content delivery, the Internet of Things, and the software supply chain.

Bio:  Vasilios Siris is Full Professor at the Department of Informatics, Athens University of Economics and Business (AUEB), where he is since 2009. Previously he was an Assistant Professor at the University of Crete (2002-2008) and Research Associate at the Institute of Computer Science of FORTH (Foundation for Research and Technology – Hellas (1992-2011). He has held visiting positions at the Statistical Laboratory of the University of Cambridge, UK, British Telecommunications (BT), UK, and the University of Bern, Switzerland. His current research interests include the application of Self-Sovereign Identity (SSI) technologies, Decentralized Identifiers, and Verifiable Credentials to the IoT, resource control in wireless and mobile networks, and architecture of future networks. He has one International and two national patents related to wireless/mobile network
management. He is the co-founder of AUEB's first spinoff, ExcID (Internet Identity, Security, and Privacy Solutions).
