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 "split" the message to acceptable pieces formula_17. Then the equations have to be built. Every single equation has the same form: The next steps sign a given message formula_8 and the result is a valid signature formula_20. The vinegar and oil variables build the pre-signature formula_24. Finally formula_25 gets transformed by the private transformation formula_5 to give the valid signature formula_27. The system of equations becomes linear if the vinegar variables are fixed – no oil variable is multiplied with another oil variable in the equation. Therefore, the oil variables can be computed easily using, for example, a Gaussian reduction
