Web2.3 Higher-Order Masking Schemes When dth-order masking is involved in protecting a block cipher implementation, a so-called dth-order masking scheme (or simply a masking scheme if there is no ambiguity on d) must be designed to enable computation on masked data. In order to be complete and secure, the scheme must satisfy the two following ... 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.
WebWe say that a randomized encryption algorithm is secure against t -th order attack (in the restricted or full model) if the distribution of any t intermediate variables can be perfectly Webencryption schemes (such as AES) and variants such as higher-order masking or a ne masking have been the topic of many recent publications. The simple underlying principle of any masking scheme is that, rather than processing the intermediate values (e.g. a key byte, plaintext byte, output of an S-box look-up)
