Question 2: (08%) DES S.Box a) Consider the above S-box used in DES algorithm. In the DES algorithm, S-box (Substitution box) receives 48 bit information from the previous step, and outputs 32 bits to the next process in each round. The 48 -bits are divided into 8 inputs of 6 -bits to the S-box. What would be the output for the following 4 inputs of 6 -bits to the above S-box? 6-bits input 1. 111101, Row: 11, C.lovmn:14 13=1101 ii. 100010 Row: 2 , Colown: 18=1000 iii. 0.00111 Row: 1 Colomin 312= troter 1100 iv. 0[11010Ra=131001
