Cryptology modular arithmetic

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. 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. That is, if a ≡b mod m then a +k ≡b +k mod m and a −k ≡b −k mod m for ...

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). http://infinitemath.com/mathforallresources/Discrete%20Math/Math%20of%20Info%20Processing/Mod%20Arith%20Crypto/ModArithCrypto.pdf
