Quark (dairy product) a somewhat crumbly texture (like ricotta). The basic quark this basic quark or skimmed quark ("Magerquark") must under German Law have less than 10% fat by dry mass. Quark with higher fat content is made by adding cream after cooling. It has a very smooth and creamy texture and is slightly sweet (unlike sour cream). A firmer version called "Schichtkäse" (layer cheese) is often used for baking. Schichtkäse is distinguished from quark by having an added layer of cream sandwiched between two layers of quark. Quark is also often sold flavored with herbs, spices, or fruit. In general, dry mass
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)
