| Abstract: | The CPA method can make affective attacks on encrypted IC chip. This method can make a detour of complex mathematical analysis on encryption algorithm and acquire ciphertext and information. CPA analysis technology plays an important role in breaking the core of device--IC chip embedded with elliptic curve algorithm. With experimental platform to acquire EC data in the encryption process, and with statistics, cryptanalysis and signal processing to make deduction and analyis, and finally to draw a conclusion, the encryption system can thus be broken successfully. |
