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 We begin by defining how to perform basic arithmetic modulo n, where n is a positive integer. Addition, subtraction, and multiplication follow naturally from their integer counterparts, but we have complications with division. Euclid’s Algorithm We will need this algorithm to fix our problems with division. dutch bangla internet bank

WebModular arithmetic. Much of modern cryptography is based on modular arithmetic, which we now brieﬂy review. We say that a≡ b(mod m) if the integers a and b diﬀer by a multiple of m. (In other words m (b− a)). The number m is called the modulus, and we say aand bare congruent modulo m. For example, 3 ≡ 17 (mod 2) because 17 − 3 is ... http://infinitemath.com/mathforallresources/Discrete%20Math/Math%20of%20Info%20Processing/Mod%20Arith%20Crypto/ModArithCrypto.pdf WebCryptography, in a broader sense, is the process of creating and analyzing protocols that prevent third parties or the general public from accessing private (encrypted) messages. Modern classical cryptography is based on several main features of information security such as data confidentiality, data integrity, authentication, and non-repudiation. cryptool online rsa
