Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What does the (n, t) in secret sharing refer to?

💡 Hint: Consider what happens when trying to reconstruct the secret with fewer parties.

Question 2

Easy

Who is the dealer in the (n, t) secret sharing method?

💡 Hint: Think about who manages the distribution of keys in a vault example.

Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

In an (n, t) secret sharing scheme, if n=3 and t=1, how many shares are required to reconstruct the secret?

  • 1
  • 2
  • 3

💡 Hint: Think about the definition of t in this context.

Question 2

True or False: A single shareholder can reconstruct the shared secret in an (n, t) scheme.

  • True
  • False

💡 Hint: Recall the minimum requirements of the scheme.

Challenge Problems

Push your limits with challenges.

Question 1

If you have 7 shareholders and want to create an (n, t) secret sharing scheme where any 4 can reconstruct the secret, describe how you would set up the polynomial for share distribution.

💡 Hint: Remember the polynomial degree must relate to the threshold policy.

Question 2

Imagine two dealers independently share the same secret using different polynomials in an (n, t) framework. What can you infer if one group can reconstruct the secret while the other cannot?

💡 Hint: Reflect on how the polynomial degree influences the threshold for reconstructing the secret.
