11.3
a. Consider the following hash function. Messages are in the form of a sequence of numbers in Zn, M = (a1, a2,cat). 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 in Table 11.1? Explain your answer. b. Repeat part (
a) for the hash function
mod n. c. Calculate the hash function of part (
b) for M = (189, 632, 900, 722, 349) and n = 989.
