Sparkle, Schwaemm and Esch

The reposiory contains the implementation of the SPARKLE family of primitives.

The Sparkle-suite is a collection of lightweight symmetric cryptographic algorithms currently in the final round of the NIST standardisation effort. It contains both Authenticated Ciphers with Associated Data (AEAD) and hash functions. Their implementation on microcontrollers is both very small (low ROM/RAM footprint) and very fast (low cycle count per processed byte).

The Sparkle paper appeared in the IACR Transactions on Symmetric Cryptology (ToSC) Special Issue on Designs for the NIST Lightweight Standardisation Process. For more information, we refer to the website sparkle-lwc.github.io.
