Assignment:
The Hawaiian alphabet has only 12 letters—the vowels. a. e. i. o. u. and the consonants. h. k, I. m, n, p, w. Assume that each vowel occurs with probability 0.116. and that each consonant occurs with probability 0.06. Also assume that the average number of information bits per letter is the same as that for the English language. Calculate the unicity distance for an encrypted Hawaiian message if the key sequence consists of a random permutation of the 12-letter alphabet.
Provide complete and step by step solution for the question and show calculations and use formulas.
