Domain-based digital-rights management system with easy and secure device enrollment
DCFirst Claim
1. A method for registering a new device as part of a domain of devices, which share rights associated with a common account, for use in accessing protected digital content within a digital-rights management system, the method comprising the steps of:
- receiving domain information corresponding to the domain of devices from a device existing within the domain of devices;
providing the domain information to a key issuer, which is separate from the domain of devices, causing the key issuer to issue a private key to the new device, wherein the private key is based on the domain information and is utilized by all devices within the domain of devices; and
receiving the private key from the key issuer for use in accessing the protected digital content within the digital-rights management system.

Abstract
New devices (101) are added to an existing domain by obtaining domain information (e.g., domain name and private domain password) from devices (101) already in the domain that preferably are in close proximity. Once the domain information has been transferred from the device already in the domain to the device being added to the domain, the device being added to the domain contacts a key issuer (105) to complete its registration into the domain. The key issuer returns a DRM domain private key (206) as well as a DRM certificate (202). Both are utilized by the device to obtain and render digital content (204).
