상관 전력 분석(CPA)은 공격자가 전력 소비와 추측된 하위 키 및 일반 텍스트 및 암호 텍스트와 같은 알려진 데이터로부터 계산된 민감한 데이터 후보 간의 상관 관계를 평가하는 암호화 모듈에 대한 잘 알려진 공격입니다. 본 논문에서는 CPA를 강화하여 새로운 일반 전력 분석을 제안합니다. 내장된 결정된 하위 키 CPA (BS-CPA)는 이전에 결정된 하위 키를 반복적으로 사용하여 민감한 데이터 후보를 계산하고 분석에서 신호 대 잡음비를 증가시켜 새로운 하위 키를 찾습니다. BS-CPA는 또한 하위 키를 찾는 반복에서 전력 트레이스를 재사용하여 모든 하위 키를 결정하는 데 필요한 총 트레이스 수를 줄입니다. BS-CPA는 sbox 출력과 같은 여러 민감한 데이터 블록이 하드웨어 구현에서와 같이 동시에 처리될 때 강력하고 효과적입니다. DPA 콘테스트에서 제공되는 전력 트레이스에 BS-CPA를 적용하여 원래 CPA보다 적은 트레이스를 사용하여 DES 키를 찾는 데 성공합니다.

Abstract: Correlation power analysis (CPA) is a well-known attack against cryptographic modules with which an attacker evaluates the correlation between the power consumption and the sensitive data candidates calculated from a guessed sub-key and known data such as plaintexts and ciphertexts. This paper enhances CPA to propose a new general power analysis, built-in determined sub-key CPA (BS-CPA), which finds a new sub-key by using the previously determined sub-keys recursively to compute the sensitive data candidates and to increase the signal-to-noise ratio in its analysis. BS-CPA also reuses the power traces in the repetitions of finding sub-keys to decrease the total number of the required traces for determining the all sub-keys. BS-CPA is powerful and effective when the multiple sensitive data blocks such as sbox outputs are processed simultaneously as in the hardware implementation. We apply BS-CPA to the power traces provided at the DPA contest and succeed in finding a DES key using fewer traces than the original CPA does.
