Token Exchange

Token exchange refers to the process of swapping one digital credential or authentication token for another, often used in federated identity systems and cloud environments to enable secure cross-platform access. In enterprise AI governance, token exchange is critical for managing access controls across multiple AI systems and ensuring that authentication credentials remain properly scoped and time-limited. Organizations implementing token exchange protocols must establish clear policies around token validity periods, revocation mechanisms, and audit logging to prevent unauthorized AI system access and maintain compliance with identity management standards.

CoSAI Paper Sets Token-Exchange Standard for Agentic Trust Boundaries

The Coalition for Secure AI has published guidance establishing token exchange at every agent trust boundary as a foundational control principle for agentic workflows. The paper addresses credential risk in agent-to-tool and agent-to-agent handoffs, where standing credentials create outsized exposure. It offers compliance teams a concrete authorization model to apply to autonomous AI deployments.
