Higher order masking of look-up tables
WebHigher-order side-channel attacks are able to break the security of cryptographic implementations even if they are protected with masking countermeasures. In this paper, we derive the best possible distinguishers (High-Order Optimal Distinguishers or HOOD) against masking schemes under the assumption that the attacker can profile. Web2 de jun. de 2024 · Running time proportion of non-linear and linear operations in AES higher order masking schemes Full size image It can be seen that linear operations account for at least 70% in these four first-order masking schemes, while they account for less than 20% in second-order masking schemes.

Web24 de mar. de 2024 · There are mainly two ways at an acceptable level of cost to solve this problem: (1) implement by look-up tables or (2) compute the unrolled functions over a finite field. The first solution costs at least 4 times more in running time than that of the second one [ 26, 27] in higher-order masked implementations.
