Abstract: Side channel attacks (SCA) use the leaked confidential data to reveal the cipher key. Power consumptions, electromagnetic emissions, and operation timing of cryptographic hardware are examples of measurable parameters (analysis) effected by internal confident data. To prevent such attacks, SCA countermeasures are implemented. Misaligned power tracks is a considerable countermeasure which directly affect the effectiveness of SCA. Added to that, SCA are suffering from tremendous types of noise problems. This paper proposes Fourth-order Cumulant Analysis as preprocessing step to align power tracks dynamically and partially. Moreover, this paper illustrates that the proposed analysis can efficiently deal with Gaussian noise and misaligned tracks through comprehensive analysis of an AES 128 bit block cipher.
