Authenticated encryption (AE) is a cryptographic construction that simultaneously protects
confidentiality and integrity. A considerable amount of research has been devoted to the …

Big data drive multidimensional convergence and profound innovations among industries
and provide novel ways of exploring the world. As they significantly create economic and …

We present the Deoxys family of authenticated encryption schemes, which consists of
Deoxys-I and Deoxys-II. Both are nonce-based authenticated encryption schemes with …

In this article, we propose two new families of very lightweight and efficient authenticated
encryption with associated data (AEAD) modes, Romulus and Remus, that provide security …

A popular approach to tweakable blockcipher design is via masking, where a certain
primitive (a blockcipher or a permutation) is preceded and followed by an easy-to-compute …

S-boxes are the only source of non-linearity in many symmetric primitives. While they are
often defined as being functions operating on a small space, some recent designs propose …

We study the security of symmetric primitives under the incorrect usage of keys. Roughly
speaking, a key-robust scheme does not output ciphertexts/tags that are valid with respect to …

We propose TEDT, a new Authenticated Encryption with Associated Data (AEAD) mode
leveraging Tweakable Block Ciphers (TBCs). TEDT provides the following features:(i) It …

We propose a new mode of operation called ZMAC allowing to construct a (stateless and
deterministic) message authentication code (MAC) from a tweakable block cipher (TBC) …

Abstract Liskov, Rivest and Wagner laid the theoretical foundations for tweakable block
ciphers (TBC). In a seminal paper, they proposed two (up to) birthday-bound secure design …
