WebMod-arithmetic is the central mathematical concept in cryptography. Almost any cipher from the Caesar Cipher to the RSA Cipher use it. Thus, I will show you here how to perform Mod addition, Mod subtraction, Mod multiplication, Mod Division and Mod Exponentiation. It is a very easy concept to understand as you will see. WebModular Arithmetic and Cryptography 12/28/09 Page 5 of 11 2. To translate numbers into characters in Problem 1, you first need to convert any given integer into an integer between 0 and 26. This is an example of what is called modular arithmetic. In particular, you are using a mod 27 system, since you are limited to the 27 integers between 0 Webmodular arithmetic. This next example illustrates this idea. Example 9: Make a table of y values for the equation y = (x +5) MOD 9 Solution: Fact: Solving equations (and congruences) if modular arithmetic is similar to solving equations in the real number system.

http://facweb1.redlands.edu/fac/Tamara_Veenstra/cryptobook/mod-math.html 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.
