WebDec 3, 2001 · Here I have assigned numerical values to the alphabet: Enciphering Step 1. Choose a 2 x 2 matrix A with integer entries to perform the encoding. (The matrix has to be invertible modulo m, but I will discuss this later) Enciphering Step 2. Group successive plaintext letters into pairs. WebAn Introduction to Modular Math. When we divide two integers we will have an equation that looks like the following: \dfrac {A} {B} = Q \text { remainder } R B A = Q remainder R. For these cases there is an operator called the modulo operator (abbreviated as mod). Modulo Operator - What is modular arithmetic?
