You are to trace the encryption and decryption process of simplified DES.

Given the $10-$bit key: $1010101010$

and $8-$bit data: $11100011$

Fill out the intermediate values in the following table:

Round key $1$: $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

Round key $2$: $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

Encryption:

After IP: $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

After f$\_$k: $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

After SW: $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

After f$\_$k: $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

Cipher text: $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

Decryption: $($use the round keys in reverse order$)$

Cipher text: $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_($should be same as above$)$

After IP: $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

After f$\_$k: $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

After SW: $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

After f$\_$k: $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

plain text: $11100011$
