  • Patent number: 9021252
    Abstract: An encrypted-traffic discrimination device includes an input interface, a flow discrimination section, a data accumulation section, a selective data calculation section, a calculation result determination section, and an output interface. The flow discrimination section discriminates the input traffic into separate flows based on at least a transmission origin address and a transmission destination address. The data accumulation section accumulates characteristic amount data of the traffic for each of the separate flows. The selective data calculation section executes an evaluation computation utilizing specific data from the characteristic amount data. The calculation result determination section that, based on a calculated evaluation computation value, executes threshold value determination to determine whether or not the traffic is encrypted, and, if the traffic is determined to be encrypted, which encryption format the traffic is encrypted with.

  • Publication number: 20130278650
    Abstract: In the present display device, LEDs are controlled to be lit up in an alternating manner where BG-LEDs (34) and BR-LEDs (35) are controlled to be lit up alternatingly every half of one frame period, such that only G display elements are used for display in a first subframe where the BG-LEDs (34) are lit up, and only B and R display elements are used for display in a second subframe where the BR-LEDs (35) are lit up. As a result, even in the case where crosstalk occurs (with respect to color filters of a certain color), display elements of colors for which such crosstalk can be inhibited or eliminated are simply used for display so that a reduction in color reproducibility can be inhibited or eliminated.
