'''Quark''' is a cryptographic [[hash function]] (family).
It was designed by Jean-Philippe Aumasson, Luca Henzen, Willi Meier and María Naya-Plasencia.

Quark was created because of the expressed need by application designers (notably for implementing [[RFID]] protocols) for a lightweight cryptographic hash function.
The [[SHA-3]] [[NIST hash function competition]] concerned general-purpose designs and focused on software performance.

Quark is a lightweight hash function, based on a single security level and on the [[sponge function|sponge construction]], to minimize memory requirements. Inspired by the lightweight ciphers [[Grain (cipher)|Grain]] and KATAN, the hash function family Quark is composed of the three instances u-Quark, d-Quark, and t-Quark. Hardware benchmarks show that Quark compares well to previous lightweight hashes.

For example, the u-Quark conjecturally instance provides at least 64-bit security against all attacks ([[Hash collision|collisions]], multicollisions, distinguishers, etc.), fits in 1379 gate-equivalents, and consumes in average 2.44 [[Watt#Microwatt|µW]] at 100 kHz in 0.18 µm ASIC.

==Implementations==
Quark is used in RFID products, but also in cryptocurrencies like PIVX.
