Interactive Quizzes

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

Question 1

What does the term (n, t) signify in secret sharing?

  • n: number of parties
  • t: minimum needed to reconstruct
  • t: number of parties
  • n: maximum allowed
  • n: party identifiers
  • t: total shares

💡 Hint: Think about what these letters usually represent in mathematics.

Question 2

True or False: If one party knows a share, they can reconstruct the secret.

  • True
  • False

💡 Hint: Consider how many pieces of the puzzle are needed to complete it.

Challenge Problems

Push your limits with challenges.

Question 1

You are required to design a secret sharing scheme for five parties where at least three are needed to reveal the secret. Describe your polynomial setup and how shares are distributed.

💡 Hint: Think about polynomial properties and how evaluating at different points works.

Question 2

Explain how the security of Shamir's scheme is upheld when parties with fewer than 't' shares attempt to reconstruct the secret.

💡 Hint: Reflect on polynomial characteristics in relation to degrees and roots.
