Abstract
A request is received at an authorization entity for access to a service producer by a service consumer. The request comprises a public key of the service consumer. The authorization entity generates an access token with the public key of the service consumer bound thereto. The authorization entity sends the access token to the service consumer. The service consumer digitally signs the access token using a private key that corresponds to the public key bound to the access token to form a digital signature. The service consumer sends the access token with the public key bound thereto and the digital signature to the service producer. The service producer validates the access token, obtains the public key from the access token, and verifies the digital signature using the obtained public key of the service consumer. The service consumer is authorized when the access token is successfully validated and the digital signature is successfully verified.
