Technologies de l'information — Techniques de sécurité — Cryptographie pour environnements contraints — Partie 5: Fonctions de hachage

ISO/IEC 29192-5:2016 specifies three hash-functions suitable for applications requiring lightweight cryptographic implementations.

- PHOTON: a lightweight hash-function with permutation sizes of 100, 144, 196, 256 and 288 bits computing hash-codes of length 80, 128, 160, 224, and 256 bits, respectively.

- SPONGENT: a lightweight hash-function with permutation sizes of 88, 136, 176, 240 and 272 bits computing hash-codes of length 88, 128, 160, 224, and 256 bits, respectively.

- Lesamnta-LW: a lightweight hash-function with permutation size 384 bits computing a hash-code of length 256 bits.

The requirements for lightweight cryptography are given in ISO/IEC 29192‑1.
