12. Maria has four-digit PIN(Personal Identification Number). She needs to send the PIN to her mother by email. Maria decides to
the PIN and uses the process:
Maria forms a 2 X 2 Matrix A from the digit of her PIN where:
A = |1* digit
|3d digit
2nd digit
4h digit
She chooses then matrix B 20 6
and calculates AB.
3
6
She performs the encoded message by writing down the four elements of AB and following them with the number of digits of each
element.
57|, the encoded message would be 125732942222. She then emailed the
32
94 encoded PIN to her mother.
For example: if AB = 12
