Abstract
Exposure of sensitive information to users is controlled using a first security token containing user identity and user credentials to represent the user who requests services, and a second security token containing two other identities, one identifying the token issuer and the other identifying the owning process. When requesting services, the token-owning process sends a security token to indicate who is making the request, and uses its key to digitally sign the request. The token-owning process signs the request to indicate that it endorses the request. A receiving server accepts a request if (1) the token-owning process endorses the request by signing the request; (2) the token is valid (token is signed by its issuer and the digital signature is verified and unexpired); (3) user entity, which can be a real user or a deployment or a server process, that is represented by the token has the authorization to access the specified resources; and (4) the token-owning process is authorized to endorse the user entity represented by the token to access the specified resources.
