Abstract:
An electrical device having a logic gate whose consumption is independent from its input data and its logic state. To this end, the device uses logic means forming switches. The interest in having a device of this type is, for example, to protect chip cards and other cryptosystems from attacks via auxiliary channels, such as collision attacks by and attacks by differential analysis of current, power or consumption. This protection is provided by the hardware. The device is for integration in all devices requiring such a protection.
