1. Explain the use of matrices in computer. (5 marks) 2. Cryptography, the science of encrypting and deciphering messages written in secret codes, has played a vital role in securing information since ancient times. More recently, with millions of financial transactions conducted over the Internet daily, cryptography has become more important than ever. Companies has begun to make online transactions more secure by installing encryption software to prevent sensitive information such as credit card numbers from falling into the wrong hands. Cryptology is real-world application of matrix inverses and used to encode and decode secret messages. Solve the problem below using the application of matrices in cryptography Coding system Each letter is assigned a number based on its position and 27 is used for a blank space A B C D E F G H I J K L M 1 2 3 4 5 6 7 8 9 10 11 12 13 N O P Q R S T UV W x Y Z 14 15 16 17 18 19 20 21 22 23 24 25 26 Blank (-)-27 An invertible matrix A, which will be used to encrypt the message is 2 3 1.
