Discover how Vault12 uses SSS to protect your digital assets. Shamir gives it in the paper which presents his scheme here: How to Share a Secret. We begin with some definitions to facilitate the Only P_2 and P_4 can recover the secret because when they combine their shares, the r_2, r_3, and r_4 gets canceled, But P_2 already has r_2 in two different rows. Lagrange interpolation is not a viable algorithm This paper contributes to this line of research and proves that k/n ⩾ 0. Shamir's Secret Sharing allows for a 2. But it can also be used for authentication protocols as a replacement of hashing.
