Semiconductor integrated circuit
A semiconductor integrated circuit includes a logic circuit including a plurality of storage elements which can each store 1-bit information and an attack detection circuit, the attack detection circuit includes an error determination circuit which can detect through a logic operation that errors have occurred in codes stored in said a plurality of storage elements, and a light irradiation detection circuit which has a light detection element and can detect light irradiation, a light detection element is disposed in the center of area for detecting light irradiation surrounding a plurality of storage elements. It is determined that the logic circuit has been attacked from outside when the error determination circuit detects an error or the light irradiation detection circuit detects light irradiation.
