  • Patent number: 10116442
    Abstract: A data storage unit (202) stores encrypted data while remaining in an encrypted state, and stores decryption conditions to define a user attribute of a decryption-permission user who is permitted to decrypt the encrypted data. In a case wherein revocation information to indicate a user attribute of a revoked user who is no longer the decryption-permission user has been added to the decryption condition when update timing arrives, a revocation information removing unit (206) removes the revocation information from the decryption condition while the encrypted data remains in the encrypted state.

To detect unauthorized, malicious or inadvertent changes to these files, either within one or more files, or by deletion, replacement or movement of files in their entirety, each file incorporates a last change timestamp and the contents of the file are digitally signed. Furthermore, every file in the secure repository is logged in an index file together with its respective change date stamp, and the index file as a whole is also digitally signed. Unauthorized changes can be identified by comparison of the file date stamps with the content of the index as well as verifying the validity of each digital signature.

  • Patent number: 9147052
    Abstract: Various embodiments utilize hardware-enforced boundaries to provide various aspects of digital rights management or DRM in an open computing environment. Against the backdrop of these hardware-enforced boundaries, DRM provisioning techniques are employed to provision such things as keys and DRM software code in a secure and robust way. Further, at least some embodiments utilize secure time provisioning techniques to provision time to the computing environment, as well as techniques that provide for tamper-resistant storage.

  • Patent number: 9146806
    Abstract: A method is for processing transmission errors during contactless communication of information between a device and a reader. The information may be transmitted in the form of frames sent to a send/receive module of the reader in contactless coupling with the device and controlled by a control module coupled to the send/receive module. The information may be extracted from the frames within the send/receive module so as to be delivered to the control module. The method may include a detection of transmission errors that are to be ignored.

  • Patent number: 9087221
    Abstract: A device for preventing logging of client input data in a computer system, characterized in that it includes a first transmission interface used to connect the smart electronic device, a second transmission interface used to connect the computer system, and a data encryption chip for encryption of the input data. The data encryption chip is set between the first and second transmission interfaces and is used to encrypt data input from the first transmission interface, and then transmit the encrypted data to the computer system via the second transmission interface. The device allows for the use of a smart electronic device as a real keyboard, and the computer system permits the data encryption chip to encrypt the data input by the smart electronic device, which are then sent to the computer system, helping to prevent logging of keying data with higher efficacy and applicability.

  • Patent number: 9076145
    Abstract: Provided are methods, apparatus and systems for the sale of digital content over a network. The disclosure herein discusses the recording of a broadcast of a digital data stream by a broadcast receiving device. A listener may select a particular digital data stream to purchase by selecting a content identifier associated with the digital data stream of interest at the recording device. Upon obtaining the selection, a purchase request message is transmitted to an intermediary communication device. The purchase request message includes at least the content identifier. After the transaction is completed at a transaction server, a purchase confirmation message including at least a digital rights management key associated with the digital data stream is returned to and received by the broadcast receiving device. Upon receipt, of the digital rights management key, the recorded digital data stream is released for reproduction.

  • Patent number: 9036819
    Abstract: The present invention provides a broadcast receiving apparatus that receives a broadcast wave containing multiple channels. The apparatus comprises, among other things, a selecting unit that selects a channel from the broadcast wave; a determination unit that determines, for all channels that can be selected by the selecting unit, whether or not the obtaining unit can obtain an encrypted second-type encryption key that can be decrypted by the decrypting unit using the updated first-type encryption key; and an updating unit that updates the computer program stored in the memory to the updated program in the case where the determination unit has determined that the obtainment is possible for all the channels.

  • Patent number: 9031235
    Abstract: In a downloadable conditional access system (DCAS), preferably all DCAS-specific code is implemented in a configurable secure (CS) processor that is in communication with the host processor. Preferably, no DCAS-specific code is executed in the host processor. The host processor delivers commands to the CS processor, which the CS processor performs to configure itself in accordance with the particular DCAS encryption scheme used by the DCAS. Once configured, the CS processor executes a DCAS software module that has been downloaded to the CS processor, which looks for the corresponding EMMs and ECMs, processes them to obtain the CW, and then uses the CW to decrypt the content stream.

  • Publication number: 20150124964
    Abstract: Embodiments of the invention provide an improved method and an improved receiver for obtaining a control word. Two or more subkeys are obtained in a receiver. Each subkey was encrypted under control of a key received in an entitlement message or transformed under control of a seed received in an entitlement message. After decryption or transformation, the subkeys are combined to obtain the control word. Typically at least one of the entitlement messages is a positive entitlement message and at least one of the entitlement messages is a negative entitlement message. Embodiments of the invention can be used in a conditional access system such as a Pay-TV system.

  • Patent number: 9014375
    Abstract: A method and apparatus for brokering the enablement of the communication of encrypted media programs from a plurality of independent broadcasters to a plurality of receivers is disclosed. The system makes use of a pairing key for each provided service, which is differently encrypted by a pairing server and by the broadcaster providing the service. The encrypted versions of the pairing key are decrypted in a first receiver module using information known to the pairing service but not the broadcaster and in a second receiver module using information known to the broadcaster. The pairing key is used to cryptographically bind the first and second receiver modules.
