XCId: An SSI-Based Cross-Cloud Identity Wallet
Cross-cloud is an emerging strategy to run ap-plications seamlessly across different Cloud Service Providers. Even though there are significant benefits such as scalability, compliance or vendor lock-in avoidance, aspects of security interoperability - particularly in the realm of identity man-agement - remains a significant challenge. In this article, we present a novel solution, called XCId, that addresses identity interoperability in cross-cloud environment without relying on intermediaries or third-party brokers. Our approach follows the Self-Sovereign Identity principles to ensure a user-centric identity solution and is built upon existing and widely deployed protocols, allowing interoperability with current Cloud Service Providers technologies. We implemented the framework and tested it on Amazon Web Service, Google Cloud platform and Own Cloud.
