  6. 10. Far Field Electromagnetic Side Channel Analysis of AES

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Zihao Zhao; [2020]
    Keywords : Side-channel analysis; far-feild electromagnetic emission; AES;

    Abstract : Side-Channel Attacks (SCAs) have become a realistic threat to implementations of cryptographic algorithms. By utilizing the unintentionally leaked side-channel information during the execution of a cryptographic algorithm, it is possible to bypass the theoretical strength of the algorithm and extract its secret key.
