Multiple key generation for securing data sharing and backup

Abstract

Currently a data sharing and data backup is been maintained by the intermediator of cloud admin provider also to reduce the cost of intermediator management and to get an authentication. It is introducing to provide a security and efficient access to large amount of outsourced data. In this project we are proposing a key distribution to solve the problem (encryption and decryption). As the user is provided two types of key by the admin to secure the data outsourcing and data backup which is been encrypted and decrypted so that threading and attacks can be reduced using cryptography based key mechanism. We are introducing a key mechanism using RSA and AES for generating keys files to secure the data. By this cryptographic key mechanism, the cloud users are free from the data management, consumption of time, cost.
