    摘要: A method for enforcing a software upgrade for software operable on a device includes receiving, at the device, a message including software-version information for the software from a domain controller. The software-version information indicates a list of approved versions of the software. The method includes determining, by the device, the software-version information from the message, and determining a current version of the software included on the device by performing a comparison of versions in the list of approved versions to the current version of the software on the device. If the current version of the software is not included in the list of approved versions, the method includes causing the device to not have or use a set of up-to-date security credentials for a set of content servers, for accessing any pieces of media on the set of content servers until the device has an approved version of the software.

    摘要: A client, method and system for registering a DRM client is disclosed. The method (100) includes the steps of: initiating (110) a registration request via a DRM client with an encrypted registration message including an asymmetric key cryptographic identity, a customer identifier and an application specific information (AINFO) field including a digital signature and a device certificate chain; validating (120) information in the application specific information (AINFO) field by a DRM registration server; and receiving (130) a registration response, the registration response being encrypted and including access information, to obtain content. Advantageously, this method provides an enhanced and reliable means of authentication.

    摘要: A content moving device may provide content to plurality of different user devices using a plurality of different DRM systems. The content moving device provides for registration of the DRM systems associated with the user devices. The content moving device may verify a user device by a DRM ID associated with the user device. A domain size may be used to limit the number of content user devices that may be approved for access.

    摘要: A method of generating a Personal Identification Number (PIN) between a first device and a second device in a network is provided. The method includes securely receiving information of input choices of the second device and random numbers assigned to the input choices at the first device. At the first device, the PIN is generated from the random numbers, and instructions are provided directing an entry of the input choices on the second device. At the second device, the input choices are entered. The second device is operable to generate the PIN from the input choices and the random numbers if the input choices are entered as instructed.
