Abstract
An electronic circuit with protection against eavesdropping, including a first circuit element embedded in the electronic circuit, a second circuit element embedded in the electronic circuit, one or more connection lines between the first circuit element and the second circuit element, a first monitoring unit in the first circuit element for measuring capacitance of at least one of the connection lines between the first circuit element and the second circuit element, wherein the first monitoring unit is configured to identify changes in capacitance of the connection lines and to initiate actions to prevent eavesdropping in response to identifying changes.
