Energy analysis attack testing device and method for RSA-CRT operation

The invention provides an energy analysis attack testing device for RSA-CRT (Received Signal Amplification-Cathode Ray Tube) operation. A data generation module generates input data C, the input dataC corresponds to the secret key p, the same position of the input data C and the high-section pH is set as pH, the same position of the input data C and the middle-section pM is traversed from all 0 to all 1, and the same position of the input data C and the low-end pL is set as all 1. The pH of the high segment is an attacked part, the pM of the middle segment is an attacked part, and the pL of the low end is an uncertain part. And the control module controls the IC chip to perform RSA encryption operation on the input data C. And the storage module stores the encrypted data M output by the IC chip. And the IC chip performs decryption operation on the encrypted data M based on RSA-CRT operation to obtain an output S. The power consumption detection module detects the power consumption ofthe IC chip during modular
