The present invention relates to a self-destructible apparatus and method. The apparatus includes a self-destructible operation unit composed of a plurality of cavity cells; a variable voltage/current supply unit configured to supply a variable voltage and current to the self-destructible operation unit; an identification (ID) matching unit configured to compare an ID input from an external source to a digital physical unclonable function (PUF) ID assigned to each of the cavity cells to determine whether the two IDs match each other so that power of the variable voltage/current supply unit is supplied to only a desired cavity cell among the plurality of cavity cells; a digital PUF ID generation unit configured to generate the digital PUF ID input to the ID matching unit; and an external ID input unit configured to generate the ID input to the ID matching unit.
A self-destructible apparatus comprising:
The self-destructible apparatus of claim 18, wherein the sampling unit comprises a plurality of D flip-flops configured to receive square wave frequencies output from the plurality of unit cells and output 0 or 1 by using a square wave frequency when a clock signal is applied.
A self-destructible method comprising:
