Question 9

9. Suppose that the message GO SOX is to be enciphered using Verman’s telegraph cipher. (a) Express the message in Baudot code. (b) If the enciphering key is 0111011110 1010110010, obtain the alphabetic form of the ciphertext. 10. A plaintext message expressed in Baudot code has been converted by the Verman cipher into the string 1100011100001111 1010010011111111. If it is known that the key used for encipherment was 0111011001010011 1100011001101010, recover the message in its alphabetic form.
