Authenticated Delegation and Authorized AI Agents
AUTHORS: South et al. | PUBLISHED & REVIEWED: 2025-01-15
CORE ARCHITECTURAL THESIS & FINDING
Establishes formal cryptographic frameworks for authenticated, authorized, and auditable delegation through scoped credentials, OAuth 2.0, and OpenID Connect.
MY INTERPRETATION
Cryptographic token scoping and explicit authorization boundaries are mandatory to prevent unauthorized tool invocations and side-effects during autonomous agent execution.
PRACTICAL IMPLEMENTATION
Engineered virtual scoped API keys and token proxy middleware in ModelSwitchyard to intercept tool dispatches and enforce granular tenant permissions.
