A cryptographic key is a value (essentially a random string of bits) that serves as input to an algorithm, which then transforms plain text into ciphertext (and vice versa for decryption). One of the important characteristics that determines key strength is its cryptoperiod [1]. Or the length of time for which the key is authorised for use. 1. From current literature survey, critically analyse and discuss cryptoperiods for hash, symmetric, and asymmetric algorithms. Find at least three sources for each of the algorithms (select two algorithms from each category). 2. Draw a table to list the algorithms and the recommend time, and then calculate the average of each. 3. Provide recommendation on the cryptoperiods for each selected algorithm.
