  • Patent number: 9794062
    Abstract: A system and method for providing a scrambled tweak mode of block cipher encryption for a device that mitigates the effect of side channel attacks based on differential power analysis (DPA). The scrambled tweak mode encryption engine creates noise at the start of the encryption process by obfuscating the counter value with the use of the very fast mixing function, such as a mixing function based on a XOR tree, substitution-permutation networks, or double-mix Feistel networks. The mixing function uses some secret key material, which diversifies its behavior between different instantiations. Because the counter values are scrambled and the mixing functions operate very fast in parallel hardware, the input of the block cipher is pseudorandom and groups of blocks can't be correlated.

    Abstract: Mechanisms for identifying hidden meaning in a portion of natural language content are provided. A primary portion of natural language content is received and a secondary portion of natural language content is identified that references the natural language content. The secondary portion of natural language content is analyzed to identify indications of meaning directed to elements of the primary portion of natural language content. A probabilistic model is generated based on the secondary portion of natural language content modeling a probability of hidden meaning in the primary portion of natural language content. A hidden meaning statement data structure is generated for the primary portion of natural language content based on the probabilistic model.

  • Patent number: 9646143
    Abstract: Systems and methods for automatically maintaining the anonymity or privacy of a stream of data as it is transmitted over a network or provided for other use, by receiving a data stream in real-time from an original source and identifying a data subset of interest within the original data stream. The data subset of interest is segregated from the data stream for either obfuscating at least a portion of the data subset in accordance with certain criteria or encrypting it. The data subset is obfuscated or encrypted for purpose of transmission over the network or for testing and reunited at a target source with the remainder of the data stream.

  • Patent number: 9521159
    Abstract: Methods and systems are provided for facilitating access to a cloud-based logging service. According to one embodiment, access to a cloud-based logging service is integrated within a network security appliance by automatically configuring access settings for the logging service and creating an account for the security appliance with the logging service. A log is created within the logging service by making use of the automatically configured access settings and the account. A request is received by the security appliance to access data associated with the log. Responsive thereto and without requiring separate registration with the cloud-based logging service, the data is retrieved by the security appliance from the logging service and is presented via an interface of the security appliance.

  • Patent number: 9497167
    Abstract: Methods and systems for filtering communication packets using a multi-stage filtering system that receives a large volume of communication packets from a communication network that filters the packets in two or more successive stages. The system comprises at least one front-end filtering unit and multiple back-end filtering units. Typically although not necessarily, the front-end filtering unit filters the packets based on layer-2 to layer-4 attributes of the packets. The back-end filtering units, on the other hand, filter the packets based on content extracted from the packet payloads. The back-end filtering units may perform filtering, for example, based on keyword spotting, application classification, malware detection and other content-related criteria. The front-end filtering unit typically performs filtering at the individual packet level and/or at the level of request-response transactions.

  • Patent number: 9491003
    Abstract: Disclosed are a method and apparatus for keeping orders among messages when transmitting and receiving messages within a Converged IP Messaging (CPM) session. A message transmission and reception method in a network comprises receiving a message including sequential identification information and a cumulative size, and outputting the received message, wherein the sequential identification information is an identifier allowing identification of orders managed within a session, transmission and reception being performed in the session, and the cumulative size is the sum of sizes of messages, the messages being sent by a subject having sent the received message within the session, wherein the output order of the received message is decided based upon the sequential identification information and sequential identification information relating to messages received prior to the received message.

  • Patent number: 9479983
    Abstract: A communication device performs a method for determining when to switch between multiple communication modes of a transceiver subsystem. The method includes detecting an indication that a multimedia message is ready for transmission. The method also includes switching, by the transceiver subsystem in response to detecting the indication, from an infrastructure communication mode to a peer-to-peer communication mode, and transmitting the multimedia message in the peer-to-peer communication mode. The method further includes determining that the multimedia message transmission is complete, and switching, by the transceiver subsystem, back to the infrastructure communication mode in response to determining that the multimedia message transmission is complete.

  • Patent number: 9443096
    Abstract: Methods and systems to allow for selective access to supplemental content that is associated with more generally distributed original content. In an embodiment, supplemental content may be encrypted, then integrated with original content using a steganographic technique. The resulting aggregated content may then be made available to users. Users may then extract the encrypted supplemental content from the original content. Those users having the proper privilege level may be given a cryptographic key to allow decryption of the supplemental content. Those without the necessary privilege will not be given this decryption key, and will therefore be unable to access the supplemental content.

  • Patent number: 9425964
    Abstract: A signal processing method for a display device is provided. The display device is capable of connecting a portable consumer electronic device via a high-definition link (MHL) port. Via the communication bus (CBUS) in the MHL port, a set of encryption codes is provided to the portable consumer electronic device. Based on an encrypted identification fed back from the portable consumer electronic device, it is determined whether the portable consumer electronic device passes authentication. If the portable consumer electronic device passes the authentication, when a human interface device provides a user command to the display device, the user command is encrypted according to the set of encryption codes to generate an encrypted user command compliant to the CBUS specification. Via the CBUS of the MHL port, the encrypted user command is provided to the portable consumer electronic device.

  • Patent number: 9355258
    Abstract: The invention relates to a system and a method for privacy preservation of sensitive attributes stored in a database. The invention reduces the complexity and enhances privacy preservation of the database by determining the distribution of sensitive data based on Kurtosis measurement. The invention further determines and compares the optimal value of k-sensitive attributes in k-anonymity data sanitization model with the optimal value of l sensitive attributes in l diversity data sanitization model using adversary information gain. The invention reduces the complexity of the method for preserving privacy by applying k anonymity only, when the distribution of the sensitive data is leptokurtic and optimal value of k is greater than the optimal value of l.
