Abstract
The disclosed technology teaches confirming delegation of authorization from an authorization server (AS) by a client to a service, including an AS issuing an OAuth2 access token in the form of a Macaroon (MAT), optionally with caveats, including a root signature, and providing the MAT to a client. Included is the client modifying the OA2 access token by appending caveats that narrow authorization, and by applying a message authentication code (MAC) chaining algorithm to generate an updated signature to include in the resulting MAT with caveats (MATwC), the client delegating authorization to a service by forwarding the MATwC to the service and the service using the MATwC to access a resource server (RS), the RS passing the MATwC to the AS, and the AS determining authenticity of the MATwC as a bearer token and evaluating scope of authorization from the MAT as narrowed by the caveats, and reporting results.
