Patent ID: 6926204

Claim:
Secure electronic device comprising at least an electronic circuit containing information to be protected, including: 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 (ref 1 , ref 2 , ref 3 ) outputting result signals, a device ( 20 ) for protection of information comprising means for triggering destruction of at least part of the circuit, a logical intrusion detection device ( 21 ) capable of activating the protection device after seeing the result signals, characterised in that it comprises firing means ( 31 ) that enable priming of a local or global pyrotechnic micro-charge ( 30 ) using electrical energy permanently stored in the energy source.
