13.In your own words explain the differences between a TRNG and a PRNG? Which one of them would you consider, if you were only interested in: (a) High entropy. (b) High speed. (c) Low runtime noise.

14.Explain how you can increase the security of the response of a weak PUF (used for key generation) against possible guessing or side-channel attacks. [Hint: One common technique is to use the hashing mechanism.]

15.Briefly discuss the quality metrics used to evaluate PUFs and TRNGs.
