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

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 …

We take advantage of a recently published open source implementation of the AES
protected with a mix of countermeasures against side-channel attacks to discuss both the …

Masking is a counter-measure that can be incorporated to software and hardware
implementations of block ciphers to provably secure them against side-channel attacks. The …

Abstract The Number Theoretic Transform (NTT) is a major building block in recently
introduced lattice based post-quantum (PQ) cryptography. The NTT was target of a number …

We revisit the popular adage that side-channel countermeasures must be combined to be
efficient, and study its application to bitslice masking and shuffling. Our contributions are …

Naïve implementation of block ciphers are subject to side-channel and fault injection attacks.
To deceive side-channel attacks and to detect fault injection attacks, the designer inserts …

In recent years, inner product masking (IPM) has been proposed as a promising code based
masking scheme against side-channel attacks. However, most studies mainly focus on …

NIST released the draft standard for ML-KEM, and we can expect its widespread use in the
embedded world in the near future. Several side-channel attacks have been proposed, and …

Physical side-channel attacks exploit a device's emanations to compromise the security of
cryptographic implementations. Many countermeasures have been proposed against these …
