Abstract

Shamir secret sharing scheme

This presentation explains how the Shamir secret sharing scheme works.

Basic idea

This scheme allows uses to break a secret into multiple pieces and enforce a minumum number of secrets out of all to be presented in order to construct the original secret reliably.

Prerequisites

High school math and some going along with intuition.
This will explain a new concept called Lagrange basis polynomial, All intuition will be given from scratch so no pre-reading required for this.

This talk will only present the content of first 2 articles in the interest of time.
