= Tropical cryptography
{wiki=Tropical_cryptography}
Tropical cryptography is a field of study that combines ideas from tropical mathematics and cryptography. Tropical mathematics is a branch of mathematics that deals with the "tropical semiring," where the usual operations of addition and multiplication are replaced by operations that involve taking minimum (or maximum) and addition, respectively. In tropical mathematics, for example, the tropical addition of two numbers is the minimum of the two, and the tropical multiplication is the usual addition.
