Ask Your TeacherMy NotesQuestion PartPointsSubmissions UsedMatrices are commonly used to encrypt data. Here is a simple form such an encryption can take. First, we represent each letter in the alphabet by a number, so let us take < space > = 0, A= 1, B= 2, and so on. Thus, for example, "ABORT MISSION" becomes[1 2 15 18 20 0 13 9 19 19 9 15 14].To encrypt this coded phrase, we use an invertible matrix of any size with integer entries. For instance, let us take Ato be the 2 ×2 matrix 3124.We can first arrange the coded sequence of numbers in the form of a matrix with two rows (using zero in the last place if we have an odd number of characters) and then multiply on the left by A.EncryptedMatrix= 3124
