WebbRivain-Prouff masking scheme is the first provably secure higher-order masking for AES [31] using addition chain, as shown in Figure 1. In this way, the AES S-Box can be masked at... WebbAbstract. Secure elements, such as smartcards or trusted platform modules (TPMs), must be protected against implementation-level attacks. Those include side-channel and fault injection attacks. We introduce ODSM, Orthogonal Direct Sum Masking, a new computation paradigm that achieves protection against those two kinds of attacks. Webb1 jan. 2015 · In this paper, we study the problem of automatically verifying higher-order masking countermeasures. This problem is important in practice, since weaknesses have been discovered in schemes that were thought secure, but is inherently exponential: for \(t\)-order masking, it involves proving that every subset of \(t\) intermediate variables is … ks2 geography city study

Webb1 nov. 2024 · This version of DPA Contest uses Advanced Encryption Standard (AES) protected against side-channel attacks using rotating s-box masking (RSM) countermeasure. The authors identify a flaw in the masking scheme that was used in this contest. More specifically, the problem lies in an unfortunate choice of values for masks. Webb28 sep. 2011 · The adaptation of the latter protocol to the context of side channel analysis results in a completely new higher-order masking scheme, particularly interesting when addressing resistance in the presence of glitches. An application of our scheme to the AES block cipher is detailed. References ks2 general knowledgeWebbMasking is a popular countermeasure as it can be proven secure against an attacker model. In practice, software-masked implementations suffer from a security reduction due to a mismatch between the considered leakage sources in the security proof and the real ones, which depend on the microarchitecture. ks2 geography bitesize
