Implementing Shamir’s Secret Sharing Scheme in Python

SSS is used to secure a secret in a distributed form, most often to secure encryption keys. The secret is split into multiple shares, which individually do not give any information about the secret. To reconstruct a secret secured by SSS, a number of shares is needed, called the threshold. No information about the … Visa mer Shamir's secret sharing (SSS) is an efficient secret sharing algorithm for distributing private information (the "secret") among a group so that the secret cannot be revealed unless a quorum of the group acts together … Visa mer Adi Shamir first formulated the scheme in 1979. Visa mer The scheme exploits the Lagrange interpolation theorem, specifically that $${\displaystyle k}$$ points on the polynomial uniquely determines a polynomial Visa mer The following example illustrates the basic idea. Note, however, that calculations in the example are done using integer arithmetic rather than using finite field arithmetic to make the idea easier to understand. Therefore the example below does not provide … Visa mer SSS has useful properties, but also weaknesses that mean that it is unsuited to some uses. Useful properties include: 1.
