This paper presents a side-channel analysis (SCA) on key encapsulation mechanism (KEM)
based on the Fujisaki–Okamoto (FO) transformation and its variants. The FO transformation …

Abstract Even today, Side-Channel Analysis attacks pose a serious threat to the security of
cryptographic implementations fabricated with low-power and nanoscale feature …

Masking has been recognized as a sound and secure countermeasure for cryptographic
implementations, protecting against physical side-channel attacks. Even though many …

Over the last years, the rise of the IoT, and the connection of mobile-and hence physically
accessible-devices, immensely enhanced the demand for fast and secure hardware …

Intellectual Property (IP) thefts of trained machine learning (ML) models through side-
channel attacks on inference engines are becoming a major threat. Indeed, several recent …

In this paper, we introduce a second-order masking of the AES using the minimal number of
shares and a total of 1268 bits of randomness including the sharing of the plaintext and key …

This work introduces second-order masked implementation of LED, Midori, Skinny, and
Prince ciphers which do not require fresh masks to be updated at every clock cycle. The …

Being based on a sound theoretical basis, masking schemes are commonly applied to
protect cryptographic implementations against Side-Channel Analysis (SCA) attacks …

This paper provides necessary properties to algorithmically secure firstorder maskings in
scalar micro-architectures. The security notions of threshold implementations are adapted …

Side-channel attacks extracting sensitive data from implementations have been considered
a major threat to the security of cryptographic schemes. This has elevated the need for …
