  • Patent number: 9755836
    Abstract: Provided are techniques to enable, using broadcast encryption, a device to locate a service offered by a server with the knowledge that the service offered by the server is a trusted service. A signed enhanced Management Key Block (eMKB) includes a trusted service locator (TSL) that includes one or more records, or “trusted service data records” (TSDRs), each identifying a particular service and a corresponding location of the service is generated and transmitted over a network. Devices authorized to access a particular service parse the eMKB for the end point of the service, connect to the appropriate server and transmit a request.

  • Patent number: 9515834
    Abstract: Provided are techniques for the distribution and control of digital content such that Quality of Experience (QoE) is maintained. Content is protected from when the content is encrypted to when it is used. To ensure the QoE of particular content, a content owner embeds a list of required or preferred components that must be employed to render the content. The content owner's list of required or preferred components specifies specific components “trusted” to correctly process the content. The specified chain of preferred components is compared to possible devices in the system that processes the content. If there are multiple acceptable devices for a specific link, a preference system is employed to determine the device that executed the particular part of the chain. The preference system is based upon a number of factors, such as, but not limited to, performance characteristics, user preferences, expected stability, power requirements and system preferences.

  • Patent number: 9009487
    Abstract: Provided are techniques for the creation and storage of an archive for binding IDs corresponding to a cluster of devices that render content protected by a broadcast encryption scheme. When two or more clusters are merged, a binding ID corresponding to one of the clusters is selected and a new management key is generated. Binding IDs associated with the clusters other than the cluster associated with the selected binding ID are encrypted using the new management key and stored on a cluster-authorized device in a binding ID archive. Content stored in conformity with an outdated binding ID is retrieved by decrypting the binding ID archive with the management key, recalculating an old management key and decrypting the stored content.

  • Patent number: 8903743
    Abstract: A method, computer program product, and data processing system for secure automated dispensing of prescription medications are disclosed. A preferred embodiment of the present invention utilizes broadcast encryption to encrypt a prescription for storage on a machine-readable medium that is pre-written with a key management block (KMB). The KMB encodes a session key needed to read from or write to the medium. Each prescription-writing device and medication dispensing device is assigned a unique set of device keys, which are used to recover the session key from the medium. Only authorized devices are able to recover the session key from a medium's KMB. Thus, only authorized devices may read or validly write prescriptions from/to the machine-readable medium. Hence, only authorized providers can write fillable prescriptions and only authorized dispensers can dispense medications to fill those prescriptions.

  • Patent number: 8862878
    Abstract: Provided are techniques to enable a device that provides a service to authorize a second device for receiving the service and the delivery of the service to the second device and other devices within a trusted network. A signed Management Key Block (MKB) is generated and transmitted over a network. Devices authorized to access a particular service parse the MKB and transmit a request. A server associated with the service determines whether or not the device is authorized to access the service based upon data included in the request. The first device may issue a challenge to the second device for authentication purposes. If service is approved, service is initiated, either from the first device or another authorized device. Devices may be organized into classes such that devices of a specific class are authorized to access the service.

  • Patent number: 8528055
    Abstract: A first message comprising a received indication of a management key block (MKB) and a received indication of an authorization table (AT) is received at a first network device from a second network device. The received indications of the MKB and AT are validated by comparing them to generated indications of the MKB and AT, respectively. A response is generated based on the validation of the received indications and transmitted from the first network device to the second network device. The generated indications and response are stored. A second message comprising a second received indication of the MKB and a second received indication of the AT is received at the first network device from the second network device. The first network device communicates with the second network device in accordance with the stored response on determining that the second received indications match corresponding stored indications.
