Abstract The National Institute of Standards and Technology (NIST) initiated a public
standardization process to select one or more Authenticated Encryption with Associated …

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 …

The emergence of the Internet of Things (IoT) has enabled billions of devices that collect
large amounts of data to be connected. Therefore, IoT security has fundamental …

Some of the well-known signature techniques like Winternitz and Lamport are not
considered to be very appropriate for the usage of hashing or smart contracts in Blockchains …

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 …

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 …

This paper presents WAGE, a new lightweight sponge-based authenticated cipher whose
underlying permutation is based on a 37-stage Galois NLFSR over F 2 7. At its core, the …

This survey presents the rich history of the Welch-Gong (WG) Stream cipher family. It has
been a long journey that lead the WG stream ciphers to become practical. The evolutionary …

Limited birthday distinguishers (LBDs) are widely used tools for the cryptanalysis of
cryptographic permutations. In this paper we propose LBDs on several variants of the …
