Summary: Since the beginning of the SHA-3 competition, the cryptographic community has seen the emergence of a new kind of primitives: the lightweight cryptographic hash functions. At the time writing this article, two representatives of this category have been published: Quark and PHOTON designed to match RFID constraints.
In this paper, we propose a third representative of this category which is called GLUON. It is based on the sponge construction model as Quark and PHOTON and inspired by two stream ciphers F-FCSR-v3 and X-FCSR-v2. From the generic definition of our lightweight hash function, we derive three different instances according to the required security level that must be reached.
For example, our lightest instance (GLUON-128/8) dedicated to 64-bit security level fits in 2071 gate-equivalents which stays competitive when compared with the parallel implementation of U-Quark. The software performances are good for GLUON-224/32, our heaviest instance.
