Efficient and Secure Data Storage in Cloud Computing Through Blowfish, RSA and Hash Function

Nirmaljeet Kaur, Harmandeep Singh

Abstract: Cloud computing is the way of providing computing resources in the form of services over internet. The cloud computing allows storing the user-s data and to measure the applications and services provided by cloud server. There is an ample data stored at cloud storage server. Security is one of the major issues which reduces the growth of cloud computing So Cloud computing entails encyclopedic security solutions. This paper presented secure file exchanging on Cloud using Blowfish, RSA and Hash algorithms which is capable of solving data security, authentication, and integrity problems of files on the cloud. Data security is improved by cryptography algorithms. The rightness of data is verified by introducing Hash techniques. Enhanced system (Blowfish+RSA+Hash value) compares with simple RSA and Blowfish on basis of some performance parameters like- throughput, encryption time, cipher text and delay time. In our enhanced system we integrate symmetric, asymmetric and Hash algorithms which provide better results for performance parameters. TPA which has to match the Hash code for the integrity of user data in cloud on behalf of Data Owners. Data Owner can get notification from TPA when the data integrity is lost.
