Cyber Defense shows that the depth of resistance is always important for the protection of applications, it is a big problem for many applications. Recently, to deal with the problem of cloud storage, audit setting and significant proposed study. Challenges, to cope with the current solution for mobile phones, especially when the customer will essentially be able to calculate such resources, bring them to the customer who will be updated with the new position of load of their secret essential key. The period of time is limited, as is. In this paper, we will be able to offer a new paradigm focus on cloud storage as possible to outsourcing customer and key updates, key updates to transparent audit. In this paradigm, it is important, then you can be efficient out of the safe party, and important updates to customer load will be minimized. TPA with our design, all legal actions of the customer, the customer is required to hold an encrypted version of a secret key. TPA secret key from encrypted download, upload new files to cloud client. In addition, the validity of our design to verify the encrypted secret key is fitted to customers with the ability to deliver TPA. Transparent resistance as possible with important performance features of the audit process, carefully designed tomake the customer. We include a formal security model definition and parameters. Safety instantiations that showcase on our detailed design and simulation shows are safe and effective performance. We further extended the system by adding concept group file sharing with read and write permissions and revoke user concept
