A Security Engineer Is Attempting to Increase the Randomness of Numbers

Multiple Choice

A security engineer is attempting to increase the randomness of numbers used in key generation in a system. The goal of the effort is to strengthen the keys against predictive analysis attacks. Which of the following is the BEST solution?

A) Use an entropy-as-a-service vendor to leverage larger entropy pools.
B) Loop multiple pseudo-random number generators in a series to produce larger numbers.
C) Increase key length by two orders of magnitude to detect brute forcing.
D) Shift key generation algorithms to ECC algorithms.
