 Ascon is a family of [authenticated encryption](https://en.wikipedia.org/wiki/Authenticated_encryption) (AEAD) and [hashing](https://en.wikipedia.org/wiki/Cryptographic_hash_function) algorithms designed to be lightweight and easy to implement, even with added countermeasures against side-channel attacks.
 It was designed by a team of cryptographers from Graz University of Technology, Infineon Technologies, and Radboud University: Christoph Dobraunig, Maria Eichlseder, Florian Mendel, and Martin Schläffer.
 
-Ascon has been selected as the primary choice for lightweight authenticated encryption in the final portfolio of the [CAESAR competition (2014–2019)](https://competitions.cr.yp.to/caesar-submissions.html) and is currently competing in the [NIST Lightweight Cryptography competition (2019–)](https://csrc.nist.gov/projects/lightweight-cryptography).
