Power side-channel attacks exploit data-dependent variations in a CPU's power
consumption to leak secrets. In this paper, we show that on modern Intel (and AMD) x86 …

Differential power analysis (DPA) is a side-channel attack in which an adversary retrieves
cryptographic material by measuring and analyzing the power consumption of the device on …

The candidates for the NIST Post-Quantum Cryptography standardization have undergone
extensive studies on efficiency and theoretical security, but research on their side-channel …

The performance of higher-order masked implementations of lattice-based based key
encapsulation mechanisms (KEM) is currently limited by the costly conversions between …

In this paper, we investigate the security of the BLISS lattice-based signature scheme, one of
the most promising candidates for postquantum-secure signatures, against side-channel …

During the last years public-key encryption schemes based on the hardness of ring-LWE
have gained significant popularity. For real-world security applications assuming strong …

We present novel and improved high-order masking gadgets for Dilithium, a post-quantum
signature scheme that has been standardized by the National Institute of Standards and …

We introduce the Sparkle family of permutations operating on 256, 384 and 512 bits. These
are combined with the Beetle mode to construct a family of authenticated ciphers …

Recently, numerous physical attacks have been demonstrated against lattice-based
schemes, often exploiting their unique properties such as the reliance on Gaussian …

With the advent of the Internet of Things (IoT), a myriad of devices are being connected to
one another in order to exchange information. This information has to be secured …
