Problem 3: (6pts) Consider a simplified version of the RC4 stream

Problem 3: (6pts) Consider a simplified version of the RC4 stream cipher, in which data and keystream bytes are 4-bits, and using BCD encoding. Assume that the initial lookup a. Show the content of the lookup table S after the initialization step. b. Show the first two keystream bytes. c. Given a two-bytes plaintext [1 11], show the corresponding ciphertext using the keystream bytes obtained in b
