Cryptography modular arithmetic
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. Webcalled modular arithmetic. Modular arithmetic is a new type of adding and multiplying for integers where integers \wrap around" upon reaching a certain number called the modulus. Usually for us we will be working mod 26 since there are 26 letters in the alphabet. Long Division Remainder Consider the long division problem 5)42 We have 5 8 R 2)42

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
Web1 Modular Arithmetic and More Historical Ciphers. In this section we use two historical ciphers to introduce modular arithmetic with integers. Even though the historical ciphers are no longer relevant, modular arith- metic is extremely important in modern cryptography, especially for asymmetric algorithms.
