Embedded systems are deployed in various domains, including industrial installations,
critical and nomadic environments, private spaces and public infrastructures. Their operation …

Authenticated encryption satisfies the basic need for authenticity and confidentiality in our
information infrastructure. In this paper, we provide the specification of Ascon-128 and …

Side-channel attacks exploit a physical observable originating from a cryptographic device
in order to extract its secrets. Many practically relevant advances in the field of side-channel …

Composability and robustness against physical defaults (eg, glitches) are two highly
desirable properties for secure implementations of masking schemes. While tools exist to …

The design of glitch-resistant higher-order masking schemes is an important challenge in
cryptographic engineering. A recent work by Moos et al.(CHES 2019) showed that most …

Abstract The Test Vector Leakage Assessment (TVLA) methodology is a qualitative tool
relying on Welch's T-test to assess the security of cryptographic implementations against …

In this paper, we provide a necessary clarification of the good security properties that can be
obtained from parallel implementations of masking schemes. For this purpose, we first argue …

Passive physical attacks, like power analysis, pose a serious threat to the security of digital
circuits. In this work, we introduce an efficient side-channel protected Advanced Encryption …

Implementing cryptographic functions securely in the presence of physical adversaries is still
a challenge although a lion's share of research in the physical security domain has been put …

We explore the concrete side-channel security provided by state-of-theart higher-order
masked software implementations of the AES and the (candidate to the NIST Lightweight …
