a. Consider the following hash function. Messages are in the form of a sequence of decimal numbers, M=(aj, a2, = at). The hash value h is calculated as (2) 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: h = - ((a))mod ni C. Calculate the hash function of part (b) for M = (189, 632, 900, 722, 349) and n=989
