The invention discloses a resisting method of a circuit on the side channel attack based on the pseudo-operation, and belongs to the technical field of computer security. A round secret key sequence is composed by m pseudo-round secret keys and one real-round secret key to conduct the first round SMS4 encrypting calculation, a second round SMS4 encrypting calculation is conducted on the result of the first round SMS4 encrypting calculation with the participation of the real-round secret key, and a ciphertext is acquired. According to the resisting method of the circuit on the side channel attack based on the pseudo-operation, the position of the generated first round SMS4 encrypting calculation is random, and an attacker cannot align with a power-consumption curve, so that the attack cannot be realized; in addition, compared with an unprotected circuit, the energy consumption cannot exceed the two times of the original energy consumption.
