Electronic circuit e.g. chip card integrated circuit, with manipulation detection provided by comparing component output signals provided in response to input signals supplied by manipulation monitoring device

摘要

The electronic circuit has a pair of components (12A,12B) providing an output signal (20A,20B) in response to an input signal (18A,18B) supplied by a manipulation monitoring device (14), with comparison of the output signals for detecting a manipulation (24A,24B). An independent claim for a method for controlling a circuit with a pair of components for manipulation detection is also included.
