Efficient algorithmic evaluation of correlation power analysis: Key distinguisher based on the correlation trace derivative

Correlation power analysis (CPA) is one of the most common side-channel attacks today, posing a threat to many modern ciphers, including AES. In the final step of this attack, the cipher key is usually extracted by the attacker by visually examining the correlation traces for each key guess. The naï...
