Quark (dairy product) branded quark, as well as other brands of quark. Quark (dairy product) Quark or quarg is a type of fresh dairy product made by warming soured milk until the desired amount of curdling is met, and then straining it. It can be classified as fresh acid-set cheese. Traditional quark can be made without rennet, but in modern dairies small quantities of rennet are typically added. It is soft, white and unaged, and usually has no salt added. It is traditional in the cuisines of German-speaking, Slavic and Scandinavian countries. Dictionaries sometimes translate it as curd cheese, cottage cheese, farmer cheese
Quark (hash function) 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 (collisions, multicollisions, distinguishers, etc.), fits in 1379 gate-equivalents, and consumes in average 2.44 µW at 100 kHz in 0.18 µm ASIC. Quark is used in RFID products, but also in cryptocurrencies like PIVX. Quark (hash function) 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)
