OAuth and Agentic Identity: The Foundation for Zero Trust AI—and What’s Next – Source: securityboulevard.com

Why OAuth Is Ideal for Agentic Identity Today—and How Maverics Makes It Real

On-Behalf-Of (OBO): Chain of Delegation

Agents act on behalf of humans or other agents. Maverics uses OAuth OBO to represent these delegation chains securely, so every agent action is traceable to its delegator and bound by policy.

Token Exchange: Multi-Hop Trust Across Clouds

Agents often need to cross trust domains. Maverics leverages OAuth token exchange (RFC 8693) to propagate identity securely across clouds and APIs, preserving trust at every hop.

DPoP: Proof-of-Possession Protects Tokens

In distributed AI ecosystems, token theft is a top threat. Maverics implements DPoP to cryptographically bind tokens to agent keys, ensuring intercepted tokens are useless without the private key.

PKCE: Secure Agent Authentication Without Secrets

AI agents often lack secure client secrets, especially in public or dynamic environments. Maverics uses OAuth PKCE (Proof Key for Code Exchange) to let agents authenticate securely without needing a pre-shared secret. This protects agent flows from interception or code injection during OAuth exchanges.

CAEP: Real-Time Zero Trust Authorization

Static token lifetimes aren’t enough. Maverics integrates CAEP (Continuous Access Evaluation Protocol) to enforce Zero Trust dynamically. If risk conditions change—due to agent behavior, location, or task—Maverics can revoke or reauthorize access immediately, not minutes later.

Attribute-Based Authorization

Beyond scopes, Maverics uses OAuth attributes and custom claims to drive fine-grained access control. Policies can evaluate who, what, for whom, for what purpose—enabling Zero Trust decisions at runtime.
