Salad salad (a noodle-based salad). The sauce used to flavor a salad is commonly called a salad dressing; most salad dressings are based on either a mixture of oil and vinegar or a fermented milk product like kefir. Salads may be served at any point during a meal: The word "salad" comes from the French "salade" of the same meaning, from the Latin "salata" (salty), from "sal" (salt). In English, the word first appears as "salad" or "sallet" in the 14th century. Salt is associated with salad because vegetables were seasoned with brine or salty oil-and-vinegar dressings during Roman times. The
Unbalanced Oil and Vinegar Unbalanced Oil and Vinegar In cryptography, the Unbalanced Oil and Vinegar (UOV) scheme is a modified version of the Oil and Vinegar scheme designed by J. Patarin. Both are digital signature schemes. They belong to the group of multivariate cryptography. The security of this signature scheme is based on an NP-hard mathematical problem. To create and validate signatures a minimal quadratic equations system must be solved. Solving equations with variables is an NP-hard problem, which means the problem is almost certainly difficult to solve efficiently in the worst case, even when using a quantum computer. While the problem is easy
