Embodiment Construction
[0024] The invention provides information security-related integrated circuits such as encryption circuits with the detection of electromagnetic fault injection attacks, and can change the number and position of the detection structures according to the needs of the circuit area, and can be well integrated with the original circuit to ensure that the attack can be detected when the attack occurs. Respond promptly.
[0025] The present invention uses a combined logic delay-based structure and a ring oscillator as an embedded detection structure, and designs a structure that can detect electromagnetic fault injection attacks for security chips such as encryption circuits.
[0026] 1. The structure for detecting electromagnetic fault injection attacks proposed by the present invention takes the combinational logic delay comparison structure and the ring oscillator as the core, and embeds them in the original circuit to form the final structure.
