  • Electronic circuit secured by disruption of its power supply
    Patent number: 10922442
    Abstract: The electronic circuit comprises a logic module performing a first function. A number generator generates a series of first numbers. A voltage generator supplies the logic module with a first minimum operating voltage of the logic module and a variable additional second voltage having electrical characteristics that are functions at least of the first series of first numbers. The variable additional second voltage comprises at least a fixed voltage defined by an offset voltage value and a first periodic voltage defined at least by a first frequency and a first amplitude. The voltage generator is configured so that the value of the offset voltage, of the first frequency and/or of the first amplitude are defined at least from the series of first numbers.
