2.4.
Het octrooi bevat de volgende conclusies, in de oorspronkelijke Engelse taal weergegeven:
1. A method for registering a new device (101) as part of a domain of devices (101), which share rights associated with a common account, for use in accessing protected digital content within a digital-rights
management system (100), the method comprising the steps of:
receiving, over a short range link (108), domain information corresponding to the domain of devices
from a device (101) existing within the domain of devices;
providing the domain information to a key issuer (105), which is separate from the domain of devices,
causing the key issuer (105) to issue a private key (206) to the new device, wherein the
private (206) key is based on the domain information and is utilized by all devices (101) within
the domain of devices; and
receiving the private key (206) from the key issuer (105) for use in accessing the protected digital content within the digital rights management system (100).
2. The method of claim 1 wherein the step of receiving the domain information for the device (101) existing
within the domain of devices comprises the step of receiving a domain name and a domain password
from the device (101).
3. The method of claim 1 wherein the domain of devices share account information.
4. The method of claim 1 further comprising the steps of:
determining (403, 405) if the domain information was received over a short-range link (108); and
not accepting (407) the domain information if the domain information was not received over the
short-range link (108).
5. The method of claim 1 further comprising the step of:
utilizing the private key (206) to decrypt a second encryption key, the second encryption key utilized
to decrypt digital content (204).
6. The method of claim 1 further comprising:
determining (403, 405) if the information was received over a short-range communication link (108);
accepting (409) the domain information only if the information was received over the shortrange
communication link (108) from another device (101) within the domain of devices, wherein providing comprises providing the domain information to the key issuer (105) causing the key issuer (105) to issue the private key (206) and a certificate (202) to the device (101), wherein the private key (206) and the certificate (202) are based on the domain information; and wherein receiving the private key (206) comprises receiving the private key (206) and the certificate (202) from the key issuer (105).
7. The method of claim 6 further comprising the steps of:
providing the certificate (202) to a rights issuer (103);
receiving an encrypted encryption key from the rights issuer (103); and
utilizing the private key (206) to decrypt the encrypted encryption key.
8. The method of claim 7 further comprising the step of:
utilizing the encryption key to decrypt digital content (204).
9. An apparatus (101) comprising:
communication circuitry (213) for receiving, over a short range link (108), domain information
(209) from a device (101) existing within 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 (100);
storage (211) for storing the domain information(209); and
logic circuitry (210) for providing the domain information (209) to a key issuer (105) which is separate from the domain of devices, causing the key issuer (105) to issue a private key (206) for use in accessing protected digital content (204) to the apparatus, wherein the private key (206) is based on the domain information (209) and is utilized by all devices (101) within the domain of devices.
10. The apparatus of claim 9 wherein the domain information comprises a domain name and a domain password.
11. The apparatus of claim 9 wherein the domain of devices share account information.
12. The apparatus of claim 9 wherein the logic circuitry (210) is configured to determine if the domain information (209) was received via short-range communication, and accept the domain information only if
the domain information was received via short-range communication from a device (101) within the domain
of devices.
13. The apparatus of claim 9 wherein the private key (206) is utilize to decrypt a second encryption key,
and the second encryption key is utilized to decrypt digital content (204).
