Building Trust in the AI Era: Agent-to-Agent Communication With DIDs and VCs - Alexander Shcherbakov, DSR Corporation
As AI moves from isolated chatbots to autonomous agent ecosystems, the "identity problem" becomes a critical security bottleneck. How does an agent verify the legitimacy of a requestor before executing a sensitive task? Traditional API keys are insufficient for dynamic, decentralized agent interactions.
This session explores a cutting-edge extension to the Linux Foundation A2A protocol that leverages Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) to establish high-assurance trust and bridges the gap between Decentralized Identity standards and AI, creating a secure backbone for the next generation of agent interoperability.
We will dive into the technical design of integrating OpenID for Verifiable Presentations (OID4VP) into agent communication flows. Attendees will learn how this proposed extension moves beyond static credentials to enable granular, verifiable Authentication (AuthN) and Authorization (AuthZ) for autonomous tasks. Beyond the protocol basics, we will analyze different patterns for VC presentation—comparing interactive vs. automated flows—and evaluate diverse wallet options, ranging from cloud-based agent wallets to secure edge implementations.
