This is a java program to encrypt a matrix using a key. The key is hidden and kept secret and inverse copy of the key is provided to the receiver, with which he/she can decrypt the matrix. The operation performed is matrix multiplication.
Here is the source code of the Java Program to Perform Encoding of a Message Using Matrix Multiplication. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.
//This is sample program to encode any 2-dimensional matrix using matrix of elememts (i+j) // for 2x2 encoding is done by multiplying given matrix with 0 1 // 1 2 import java.util.Scanner; public class Encoding_Matrix { public static void main(String args[]) { int n; Scanner input = new Scanner(System.in); System.out.println("Enter the base of squared matrices"); n = input.nextInt(); int [][] a = new int[n][n]; int [][] b = new int[n][n]; int [][] c = new int[n][n]; System.out.println("Enter the elements of matrix to be encoded: "); for(int i=0; i<n; i++) for(int j=0; j<n; j++) a[i][j] = input.nextInt(); for(int i=0; i<n; i++) for(int j=0; j<n; j++) b[i][j] = i+j; for (int i = 0; i < n; i++) { for (int j = 0; j < n; j++) { for (int k = 0; k < n; k++) { c[i][j] = c[i][j] + a[i][k] * b[k][j]; } } } System.out.println("The Encoded matrix is:"); for(int i=0; i<n; i++) { for(int j=0; j<n; j++) { System.out.print(c[i][j] + " "); } System.out.println(); } input.close(); } }
Output:
$ javac Encoding_Matrix.java $ java Encoding_Matrix Enter the base of squared matrices 2 Enter the elements of matrix to be encoded: 1 5 3 9 The Encoded matrix is: 5 11 9 21 Enter the base of squared matrices 3 Enter the elements of matrix to be encoded: 1 2 3 4 5 6 7 8 9 The Encoded matrix is: 8 14 20 17 32 47 26 50 74
