The invention discloses a chip safety evaluation method based on electromagnetic side channel analysis and a related device. The method includes: calling RSA algorithms, enabling the target antenna toexecute modular exponentiation operation; then acquiring an acquisition signal radiated when the target chip executes modular exponentiation through an antenna within a preset distance from the target chip, wherein an electromagnetic probe does not need to be close to the surface of a target chip to detect electromagnetic leakage in a short distance; carrying out spectrum analysis on the collected signals to determine the radiation frequency; carrying out waveform analysis on a preset frequency band range signal of the radiation frequency; decrypting the modular square modular multiplicationsequence obtained by analysis; obtaining the security evaluation result of the target chip according to the corresponding relation between the decryption result and the security evaluation result, wherein the security evaluation mode is attached to the actual attack scene, and the technical problem that electromagnetic leakage caused by close-range detection chip operation adopted in an existing chip security evaluation method does not conform to the actual attack scene is solved.
Description
technical field [0001] The present application relates to the technical field of chip security, in particular to a chip security assessment method based on electromagnetic side channel analysis and related devices. Background technique [0002] Side-channel attack is an effective method to evaluate chip security. The existing electromagnetic-based side-channel analysis method is to use electromagnetic probes close to the chip surface to detect the electromagnetic leakage of chip operations at close range. However, in many actual attack scenarios, it is impossible to physically touch the chip. For example, electromagnetic attacks usually use a dedicated magnetic field antenna close to the target chip to achieve the attack purpose. Therefore, long-distance detection of chip side channel leakage is more in line with actual attack scenarios.
