P-Boxes and S-Boxes Design a formulation table for a P-box that takes 8 bits as input, It outputs the bits in the even-numbered positions of the input word and removes the bits in the odd-numbered positions. Relative positions of the other bits should not be changed. What is the size of P-box in ? What is the type of P-box in ? Is the P-box in invertible? Using the DES S-box 1 table below, list the output for the following blocks of bits.
