Assume that messages are in the form of summation of decimal numbers (a_1, a_2, a_3, ..., a_t): M = sigma_i = 1^t a_i Consider the following sequence of decimal numbers (5, 9, 32, 15, 6) representing a message and answer the following questions: Calculate the Message Authentication Code based on the following hash function (H) assuming n = 23. Show your calculations. H = (sigma_i = 1^t (a_i times 2/i + 1)) mod n Explain whether this hash function satisfies any of the requirements for a hash functions. Assume p = 11, q = 7, e = 5. What is the Cypertext C? Show your calculations
