Let's say you are looking to collect some randomness from your computer. At a given time stamp, you can always collect the following 16bits as part of the time stamp:
- First 5 bits are fixed and always the same
- The next 4 bits are not perfectly random and exhibit a probability of 1/8 for the different possibilities
- Finally the last 7 bits are perfectly random, always
What would be the min entropy of one time stamp?
My intuition thinks the min entropy would be 3 bits (from the 4 imperfect bits) + 7bits from the last section, giving Min Entropy = 10 bits for one time stamp. Does this make sense?
EDIT: Rephrased the 2nd bullet point
