    Abstract: The present method of providing element a random for a cryptographic algorithm is implemented by an electronic calculator comprising a core and a set of memory/memories, the set of memory/memories including a reference memory having an intrinsic randomness in a predefined state of generating randoms.
    The method comprises:



    reading a reference message in a first memory zone, the first memory zone being included in the reference memory, the reading step being performed in the state of generating random elements of the reference memory;
    writing the reference message in a second memory zone, distinct from the first memory zone, the second memory zone being included in the set of memory/memories;
    subsequent reading of the reference message in the second memory zone, the reference message read in the second memory zone forming the random element for the cryptographic algorithm.

    Abstract: A method for transferring an adhesive layer of thermoplastic polymer(s) from a first substrate to a second substrate including: depositing an antiadhesive layer on a first substrate, this layer being deposited on the periphery of the top face of said substrate, referred to as peripheral layer, thus providing on said top face a zone devoid of said layer, referred to as central zone; depositing an adhesive layer of thermoplastic polymer(s) on said central zone; depositing an antiadhesive layer on a second substrate, this layer being deposited on the top face of the second substrate excluding its periphery, said periphery being thus devoid of said antiadhesive layer; bonding the first substrate and the second substrate consisting of thermocompressing the top face of the first substrate onto the top face of the second substrate; removing the first substrate, whereby the second substrate remains, of which the top face is coated by the adhesive layer of thermoplastic polymer(s).

    Abstract: A method for detecting an anomaly in operating a battery using a battery management system, including an acoustic receiver attached to a battery wall, and a calculating system connected to the acoustic emitter and the acoustic receiver, a mapping defining a first operating region termed the normal operating region, a second operating region termed the at-risk operating region and a third operating region termed the dangerous operating region, the method including at least one first measurement cycle, each being separated from the preceding measurement cycle by a measurement period, each measurement cycle including receiving an acoustic signal by the acoustic receiver, the received signal being transmitted to the calculating system to obtain a measurement point in the mapping; determining the operating region in which the measurement point is located; and when the measurement point is located in the at-risk operating region or in the dangerous operating region, detecting an anomaly.

    Abstract: A system and method for controlling operating modes of a system, each operating mode being implemented by an execution of one or more software components. This control system includes software components called elementary components, each elementary component having at least one input able to receive input data and/or at least one output able to transmit output data; and at least one software meta-component including one or more internal wiring diagrams, each internal wiring diagram defining interconnections between inputs and outputs of elementary components and/or meta-components, a transition logic between states defining a current state of said system and a sequence between states at least some of the states corresponding to an implementation of an internal wiring diagram, a mechanism for controlling the internal configurations, and a programming interface providing services/functions implementing at least one internal wiring scheme.

    Abstract: The invention relates to a method and a system for the automated detection of the risk of fraud in a monitored system, based on data streams generated by said monitored system and characterizing events performed or generated by operators in said monitored system. The method includes: a pre-processing (30-38) of at least one set of data recorded over a period of time, so as to obtain a subset of critical events associated with an operator; the iterative application of a first parameterized estimation process (52,56) for a risk of fraud, so as to obtain a first legitimacy score and a first associated probability of occurrence; the iterative application of a second parameterized estimation process (54,58) for a risk of fraud, so as to obtain a second legitimacy score and a second associated probability of occurrence, and the comparison (60) of the results of said first and second processes, for determining (64) whether said operator is a legitimate operator or a fraudulent operator.
