    摘要: A technology provides secure data backup and recovery for an electronic device (100) having a device identification (115) that is unique and unalterable. A method of the technology includes identifying (205) backup data (405, 805, 1205) to be backed up, encoding (210) a backup data set by coding the device identification (115) and the backup data (405, 805, 1205) for integrity and authentication using a cryptographic key (110) and an integrity function, generating (220) decoded backup data (635, 1015, 1435) and decoded device identification (640, 1020, 1440) by decoding a retrieved backup data set (605, 1005, 1405) using the the cryptographic key (115) and the integrity function, and restoring (225) the backup data with the decoded backup data only when the integrity has been verified and the decoded device identification and the device identification match. Three methods of encoding and decoding are described.

    摘要: A portable electronic device (110) contains an application revocation list (ARL) in memory (135) comprising at least one application identifier (AI) uniquely identifying an application. The portable electronic device also contains an application list memory (133) for storing at least application identifiers for trusted applications in the device. A processor (120) operatively connected to the memory determines whether an application identifier on the application revocation list matches an application identifier on the portable electronic device, and, if so, processes a revocation of the application. The application revocation list can be wirelessly updated. Application software in a portable electronic device can thus subsequently be revoked through operation of this application revocation list. A remote server (140) makes application revocation lists available to portable electronic devices over a network such as a cellular system.

    摘要: A method and system for registering a user device in a domain of a domain authority (106) using biometric information is provided. The method includes sending (402) a request (by the user device) to the domain authority for joining the domain. The user device making the request is then authenticated (400) and the biometric information of the user is then requested (406). Further, the method includes authenticating (412) the biometric information of the user. The security information of the domain is transferred (414) to the user device once the authentication of the user device and the biometric information are both successful.

    摘要: A portable electronic device (110) is capable of secure inter-processor communications (160) between processors (120, 130). The processors have unique and unalterable device identifiers used to encrypt session key data using shared secrets. A first processor device identifier is encrypted by a first processor (120) and decrypted by a second processor (130) and compared against a known device identifier to verify authenticity. Then the second processor (130) likewise encrypts and the first processor (120) likewise decrypts and likewise compares device identity to verify authenticity.

    摘要: 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).
