ALTERNATIVE TO SHAMIR’S SECRET SHARING SCHEME LAGRANGE INTERPOLATION OVER FINITE FIELD
Vanashree Gupta, Smita Bedekar · International Journal of Technical Research & Science · 2021
Secret Sharing is a robust key management method in which shares are distributed to parties and only authorized subsets of parties can reconstruct the secret.Secret sharing schemes are the tool used in cryptography and security.There are different methods of secret sharing.Threshold secret sharing is a method in which out of all the parties only predefined or certain number of parties can reconstruct the secret.In this paper we will describe a threshold secret sharing scheme, the Shamir's secret sharing scheme and proposing an alternative approach for secret recovery instead of Lagrange interpolation over finite field.Based on this study we can use it in different applications such as secret data hiding and authentication, audio secret management, medical image security and EPR hiding, in storing credit card information securely.
