A Simple and Secured Cryptography System of Cloud Computing


Cloud computing is a vast growing technology in the IT industries. Cloud Service Providers (CSP) are offering various suitable and flexible services to the users. Users of cloud computing are growing in an equal rhyme. As cloud computing is becoming an essential part of human life, users and CSP are noticing for suitable security feathers. Many researchers are working in the security aspects of cloud computing. In this paper, we present a suitable cryptography and secure authentication system for cloud computing. This procedure includes auto encryption and KEYs changing process in the cloud end. New generated KEYs will not be sent to users initially. Users will be checked in three steps for authentication. CSP can trigger encryption process at any time manually or it will be performed automatically after logged out by the users. This procedure will ensure extra security for data/files as well as prevent hackers from getting original files/data even they got valid credential. Proposed protocol is simulated by CloudSim and we observed that one more step needs for user’s credential, it required a bit of time to use data/files for only the first time. This bit of time is negligible and we can exclude it from consideration but security increase more and more.
