Abstract
A client device communicates with a target entity server and one or more third party devices. The client device has a client credential that includes a client public key and a client certificate chain. The client certificate chain includes a chain of human-readable names. The client device delegates a third party device access to a service on the server by creating a delegate certificate chain for the third party device. The delegate certificate chain is bound to a public key for the third party device and includes a human-readable name with an extension selected for the third party device. The delegate certificate chain also may include a section of the human-readable name that identifies the client device. The client device transmits or otherwise presents the delegate certificate chain to the third party device.
