Cloud computing enables to connect large groups of remote servers that support centralized data storage and online access to computer services or resources. The cloud technology facilitates to store the large amount of private and sensitive data in the public and insecure third party environment.
This makes several security related threats to the data stored in the cloud and we have come up with a solution to tackle the problem of security weakening at user end computing. In this paper, we have comprehensively addressed the timing attack by introducing Modified RSA engine in cloud environment.
