Abstract
Technology is shown for dynamically attaching secure properties to an identity certificate. Claims determining secure properties for an identity are signed and embedded in an identity certificate. Both the identity certificate and the signed claims in the certificate are verified. When a service request is received from the identity, the signed claims from the identity certificate are checked to determine if the request is permitted. If the request is permitted, then the service request is processed. Some examples involve creating claims determining the secure properties for the remote machine, signing the claims to create the signed claims, distributing the signed claims to a certificate authority, embedding the signed claims in the remote machine identity certificate, and distributing the remote machine identity certificate. The claims can be embedded in the certificate as X.509 properties.
