Welcome to the Code Lesson on HOW TO break substituion ciphers. The simplicity of this code is not to say that it has no application. We will use alphabet ciphers to represent our message and examine ways to break these codes. Then we will discuss how to break a ciphered sample.
First, here is a word about the class and the instructor.
The name of the class at USCA is Discrete Mathematics. You will wonder when you see no numbers how this can be a mathematics class. Much of mathematics is without numbers! In this particular case, frequency of use of particular letters and patterns of letters in the English language are very well suited to the study of mathematics because mathematicians study patterns of numbers and derive ways to predict data. We think of making order from chaos, and it is like a puzzle to those of us who love it! The class of students find the study of discrete mathematics refreshing and appreciate having mathematics without algebra or calculus even though they are using some of the exact same techniques to problem solve!
