Show hintHide hint
What does the 'n' signify?
Question 2.
List one practical example where secret sharing may be useful.
Show hintHide hint
Think of scenarios where multiple people have access to sensitive information.
3Question 3.
What does 't' represent in the (n, t) secret sharing scheme?
- Total shareholders
- Threshold for reconstruction
- Secret value
Show hintHide hint
