A. Consider the following hash function. Messages are in the form of a sequence of decimal numbers, M = (a1, a2, ..., at).The hash value h is calculated as for some predefined value n. Does this hash function satisfy any of the requirements for a hash function listed under the subtopic 2 "Hash Function Requirements" of topic 3 "Secure Hash Functions" of the module or the Section 3.2 of the textbook? Explain your answer. b. Repeat part (a) for the hash function: c. Calculate the hash function of part (b) for M = (189, 632, 900, 722, 349) and n = 989.
