This repository includes multiple hardware implementations of Sparkle Lightweight cipher

Sparkle is one of the ten finalist in NIST Lightweight Cryptography (LWC) standardization process.

Alzette is a 64-bit S-box based on Add-Rotate-XOR (ARX) paradigm. In this diagram, the transformed block b is split into two halves: x := b[31..0] and y := b[63..32].

Sparkle is a family of cryptographic permutations relying on using the ARX S-box.

Schwaemm is an AEAD algorithm that uses the Sparkle permutations
