Subsequently, distributed storage ought to have some system which will determine storage correctness and trustworthiness of data stored on a cloud. The main issue of distributed storage is security. Numerous scientists have proposed their work or new encryption algorithms to accomplish security or to resolve this security issue. The proposed encryption scheme leverages to build a secure data storage to significantly improve the security.
