Abstract
Domain membership vouchers are transmitted to devices in response to domain membership requests and domain joining requests. These vouchers include domain identifiers and domain keys encrypted with the public keys of the requesting devices. Once received, the domain membership vouchers establish the devices as members of authorized domains. Such authorized domains allow the sharing of protected content among devices within a particular authorized domain.
