Given the following S-Boxes:

S1=[15 10 25

84 116

1 0 14 7

93 12 13 ];

S2=[ 4 0 15 10

8 97 13

51 6 11

23 14 12 ];

Plain text: P = [a1 a2 a3 a4] where a1..a4 are 4 bits each

Key: K = [k1 k2 k3 k4] where k1..k4 are 4 bits each

Cipher text:C = E(p) = [ S1(a2k1) S2(a4k3) S1(a1k2) S2(a3k4) ]

Example:P = [1000 1100 1101 0110],K = [0001 0011 0010 1111]

C = [S1(1101) S2(0100) S1(1011) S2(0010 ] = [6 0 12 5]

= [0110 0000 1100 0101]

Question: To draw a chart showing the relation between P, C, and K according to this cipher.
