The symbol is magnified and shown in Figure 1 with a grid superimposed. Figure 1 The image in Figure 1 is to be encoded and encrypted using the following steps: 1. Each of the five horizontal rows of the picture is encoded as a 5 -bit binary number. White squares are encoded as 0 s and black squares as 1s. The horizontal rows are therefore encoded as: Row 1: 00110 Row 2: 01001 Row 3: 11100 Row 4: 01000 Row 5: 11110 2. Starting from the left, the first binary digit is multiplied by 16 , the second by 8 , the third by 4 , the fourth by 2 , and the fifth by 1 . This will convert the 5-bit binary numbers to decimal numbers as shown below: Row 1: (016)+(08)+(14)+(12)+(01)=0+0+4+2+0=6. Row 2: (016)+(18)+(04)+(02)+(11)=0+8+0+0+1=9. Row 3: (116)+(18)+(14)+(02)+(01)=16+8+4+0+0=28. Row 4: (016)+(18)+(04)+(02)+(01)=0+8+0+0+0=8. Row 5:(116)+(18)+(14)+(12)+(01)=16+8+4+2+0=30. 3. The decimal number representing each row is encrypted using modular addition with a modulus of 32 and a key of 19. 4. The result of each row is converted to a 5 -bit binary number. Use Steps 1 to 4 to work out the 5-bit binary number of each row. Show your working
