摘要：Cloud computing is the way of providing computing resources in the form of services over internet. Thecloud 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 ofcloud computing So Cloud computing entails encyclopedic security solutions .This paper presented secure fileexchanging on Cloud using Blowfish, RSA algorithms which is capable of solving data security, authentication, andintegrity problems of files on the cloud. Data security is improved by cryptography algorithms. The rightness of data isverified by introducing techniques. Enhanced system (RSA value) compares with simple RSA and Blowfish on basis ofsome performance parameters like:- throughput, encryption time ,cipher text and delay time . In our enhanced systemwe integrate symmetric, asymmetric and algorithms which provide better results for performance parameters .TPAwhich has to match the code for the integrity of user data in cloud on behalf of Data Owners. Data Owner can getnotification from TPA when the data integrity is lost. If any unauthorized person access the data in cloud, they will beblocked.
