D4.2 is a demonstrator deliverable presenting the prototype-level communication flows of the DOSS Supply Trust Chain, with the Device Security Passport Platform (DSPP), a microservices-based platform as the central integration point that securely stores, retrieves, and distributes Device Security Passports and related security evidence among IoT supply-chain actors. It describes the platform’s architecture, APIs, security model, workflows, and deployment options, as well as its integration with the DOSS modules – Component Tester, Digital Cybersecurity Twin, Architecture Security Validator, Onboarding Platform – and the pilot environments.
Overall, the prototype establishes a secure, standardized communication framework that enables automated security assessment, controlled information sharing, and continuous trust management across the IoT supply chain.
