(5 points) The following hash function takes a message M = (ay, A2, ..., an), where a; E ZK = {0,1,2, ..., k 1), and generates its hash value h: h= (a;)4 ) mod k. i=1 In the above formulation, x mod y = x - yx [] a. Does this hash function satisfies the collision resistance property? Explain your answer. b. Calculate the hash function for M = (187,492,501,413,125) and k = 571
