    摘要: Systems and methods for side-channel monitoring a local network are disclosed. The methods involve generating a program trace signal from at least one of power consumption, electromagnetic emission, or acoustic emanation of a control processor connected to the local network and operating a monitoring processor to detect a communication of a message on the local network; identify at least one purported control processor related to the communication; analyze the program trace signal of the at least one purported control processor relative to the communication; and at least one of an authenticate or verify one or more purported control processors of the at least one purported control processor based on the program trace signal of the at least one purported control processor.

    摘要: Systems and methods for non-intrusive program tracing of a device are disclosed. The methods involve generating a program trace signal from at least one of power consumption and electromagnetic emission of the device; digitizing and decomposing the program trace signal into at least two digital program trace component signals including a low frequency program trace component and one or more high frequency program trace component signals; classifying fragments of the at least two digital program trace component signals of the program trace signal as at least one of a known portion of program code and an observed behavior of the device. Each of the at least two digital program trace component signals have different frequency bands and the bandwidth of each program trace component signal is smaller than the bandwidth of the program trace signal. Each of the high frequency program trace component signals include an envelope.

    摘要: The system is based on the arrangement of a plurality of terminals (1), (I′) . . . (In), which are interconnected with one another to form a digital network by means of two databuses, one write and one read, by means of differential transmission, with a hybrid connection topology based inter alia on UTP-type cables (4). Each terminal is constituted by a DLP-type card (7), which contains a programmable logic device for the management of a series of cards associated with the card (7), said cards being a main card (8) and a user-interface card (9), which enable the user to configure the various system options, it being possible, also, to incorporate one or more extension cards (H-H′) for the input and output of audio/video signals, the Internet, a telephone line or an automatic-door-entry line, and also a remote-control and alarm card (10) for activating external loads, activating alarms and receiving signals originating from sensors.

    摘要: A vertical mother-progeny transmission route of human herpesviruses has been discovered that allows developing an animal model that is useful for identifying compounds that are potentially useful in treating and/or preventing infections and diseases caused by human herpesviruses. The method for identifying such compounds comprises experimentally infecting a non-human female animal with human herpesviruses, before or after administering the compound to be tested, crossbreeding her with a male of the same species and analyzing the presence of human herpesviruses in the progeny and/or determining the effect of said compound on the progeny or the mother. Alternatively, the compounds to be tested can be administered to the descendants carrying human herpesviruses instead of the mother and the effect on such animals is analyzed.
