a) Consider the following letter encodings:letter A E I M O R T Vencoding 000 001 010 011 100 101 110 111A message M = MARIO is Vernam encrypted into ciphertext C =AOAMV ; C = M © K where © shows modulo 2 XOR operation. Find the corresponding encryption key. Provide details of your cryptanalaysis.b) Consider the following two ciphertexts C1 = IEEIA and C2 = ORV RO that are obtained from messages M1 and M2 respectively under the vernamencryption and the same encryption key. Encrypted messages are two names.Let us denote with mi;k the kth letter in message Mi. The following is known about messages (names): m1;1 = R and m2;4 = T. Using this information,try to recover messages M1 and M2, as well as the encryption key. Provide details of your cryptanalysis.
