(b) Assume Bob has designed a hash function as follows: His function gets the data to be hashed. Then, he flips a coin 256 times, so he generates a string of Hs (Heads) and Ts (Tails). He replaces H with 1 and T with 0. After that, he writes the data along with the generated binary string which is 256 bits long in a database. Next time, his function searches the data first. If it finds the data inside the database, it immediately returns its binary string, otherwise, it will repeat the process of flipping the coin. Based on the different features that a cryptographic hash function should have [3 marks], explain if this function is a proper hash function or not [2 marks]? Examine at least THREE features [3 marks]. (8 marks)
