http://www.shodor.org/interactivate/lessons/ClockArithmetic/ WebIn mathematics, modular arithmeticis a system of arithmeticfor integers, where numbers "wrap around" when reaching a certain value, called the modulus. The modern approach to modular arithmetic was developed by Carl Friedrich Gaussin his book Disquisitiones Arithmeticae, published in 1801.

WebThe RSA cipher, like the Diffie-Hellman key exchange we have already worked with, is based on properties of prime numbers and modular arithmetic. Alice chooses two different prime numbers, P and Q, which she keeps secret (in practice, P and Q are enormous — usually about 100 digits long). WebI have tried to order my pages so that the parts most relevant to cryptography are presented first. Modular Arithmetic We begin by defining how to perform basic arithmetic modulon, where n is a positive integer. Addition, subtraction, and multiplication follow naturally from their integer counterparts, but we have complications with division.

WebModular arithmetic is basically doing addition (and other operations) not on a line, as you usually do, but on a circle -- the values "wrap around", always staying less than a fixed number called the modulus. To find, for example, 39 modulo 7, you simply calculate 39/7 (= 5 4/7) and take the remainder.
