Modular arithmetic enables us to simply make groups, rings and fields which are the basic constructing piece of most modern public-key cryptosystems.For instance, Diffie-Hellman need the multiplicative group of integers modulo a prime pp. There are different groups which can work. Modular or clock arithmetic is arithmetic on a circle rather than a number line modulo N, it can use only the twelve entire numbers from 0 through N-1.Modular arithmetic is very well understood in method of algorithms for several basic operations. ...
