Toward Improving Secret Sharing Scheme Based on Encryption in Cloud Computing Environment

Abstract

Flexibility, acceptance of hire of Cloud Computing, control facilities originates a number of challenges. In precise, safety has been widely conveyed to create the key issues which stop movement to the cloud. Shamir’s Secret Sharing Scheme splits the secret message into n shares with threshold k and distribution of shares to n participants and each participant has unique share of secret message. For reconstructing the secret message, minimum k fragments are required. Threshold scheme which requires only k shares to re-construct the secret message is implemented, as collection of shares from all the n participants to reconstruct the secret message may be unfeasible. AES encryption turns out to be totally inappropriate if a password is used as an alternative of providing the key. The attacker finds file, downloads Ax crypt, and brute force/dictionary attacks it until it’s cracked. An additional security can provided to user password which of varying length by splitting the password into n shares. Advance Encryption Standard (AES) procedure is implemented to encipher the produced shares. AES with 256-bit key is applied to encode the share for every member. Covering arrangement alternative to Boolean masking established on Shamir’s Secret Sharing arrangement is suggested.
