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

Lightweight cryptography has been one of the" hot topics" in symmetric cryptography in the
recent years. A huge number of lightweight algorithms have been published, standardized …

We propose a new class of post-quantum digital signature schemes that:(a) derive their
security entirely from the security of symmetric-key primitives, believed to be quantum …

We explore cryptographic primitives with low multiplicative complexity. This is motivated by
recent progress in practical applications of secure multi-party computation (MPC), fully …

Designing an efficient cipher was always a delicate balance between linear and non-linear
operations. This goes back to the design of DES, and in fact all the way back to the seminal …

Traditionally, countermeasures against physical attacks are integrated into the
implementation of cryptographic primitives after the algorithms have been designed for …

In this paper we investigate relations between several masking schemes. We show that the
Ishai–Sahai–Wagner private circuits construction is closely related to Threshold …

In typical applications of homomorphic encryption, the first step consists for Alice of
encrypting some plaintext m under Bob's public key pk pk and of sending the ciphertext c …

The linear layer is a core component in any substitution-permutation network block cipher.
Its design significantly influences both the security and the efficiency of the resulting block …

Symmetric ciphers purposed for Fully Homomorphic Encryption (FHE) have recently been
proposed for two main reasons. First, minimizing the implementation (time and memory) …
