The invention relates to a system for detecting the safety performance of a safety chip under induced error attacks. The system comprises a control unit, a result analysis unit and an attack device, wherein the control unit controls a safety chip encryption and decryption functional unit to carry out encryption and decryption calculation under the induced error attacks; the result analysis unit reads a encryption and decryption calculation result and compares the result with a built-in reference result; the attack device performs the induced error attacks on the safety chip under the control of the control unit. Therefore, the safety chip and the attack device are combined together through the control unit, the calculation result, under the induced error attacks, of the encryption and decryption functional unit is analyzed through the result analysis unit, and after an error is caused on the encryption and decryption calculation result, the attack device is controlled by the control unit to position coordinates of the positions, on the safety chip, of the induced error attacks as fault point coordinates, so that the system effectively detects the safety performance of the safety chip and positions the fault points.
