In this paper, we present improvements of the algebraic side-channel analysis of the Advanced Encryption Standard (AES) proposed in the works of M. Renauld and F.-X. Standaert. In particular, we optimize the algebraic representation of both the AES block cipher and obtained side-channel information, in the form of Hamming weights of intermediate states, in order to speed up the attack and increase its success rate. We study the performance of our improved attack in both known and unknown plaintext/ciphertext attack scenarios. Our experiments indicate that in both cases the amount of required side-channel information is less than the one required in the attacks introduced earlier. Furthermore, we introduce a method for handling erroneous side-channel information, which allows our improved algebraic side-channel attack (IASCA) to partially escape the assumption of an error-free environment and thus become applicable in practice. We demonstrate the practical use of our IASCA by inserting predictions from a single-trace template attack. |
