ABSTRACT:
This invention relates to a secure electronic device comprising:at least an electronic circuit (10) containing information to be protected,an energy source (11);at least one sensor (12, 13, 14) capable of measuring a determined physical magnitude and outputting a value representative of this magnitude,means (15, 16, 17) of comparing each value with at least one predefined threshold (ref1, ref2, ref3) outputting result signals,a device (20) for protection of information comprising means for triggering destruction of at least part of the circuit using pyrotechnic means (27),a decision-making logical device (21) capable of activating the protection device after seeing the result signals,firing means (31) capable of priming a local or global pyrotechnic micro-charge (30) using electrical energy permanently stored in the energy source.
