We would like to provide the benefits of cloud computing without any troubles to propel in the direction it is designed for. This is to be achieved by preventing the owner's data from all risks associated and providing a cloud model that is more secure and efficient. The proposed model shall overcome the security risks defined by the security functions over cloud computing, as follows in (Passent M. et al., 2015):

The main issue that slows down the growth of cloud computing is security. No matter how many security management tools are released or assurances of reliability are made, complications with data privacy and data protection continue to plague the market. Covering all potential security issues in this article is simply impossible. This is because of the fact that we 're still discovering many of the security issues which challenges cloud computing as it is still a work-in-progress. Cloud Computing is rapidly evolving and hence what we see today may quickly become irrelevant.

One of the major issues slowing cloud computing growth is security. No matter how many security management tools are released or assurances of reliability are made, complications with data privacy and data protection continue to plague the market.

The infrastructure of the cloud provides a multi-tenant configuration in which software deployed in virtual machines, is accessed by multiple users concurrently across heterogeneous environments. Though verifying software through evidence can provide a means for trust, the consumer would demand the authenticity of that trusted service. The possibilities for the consumer not able to fully trust are that, there is no governance or authority to certify the resources. Hence a third party authority generally called as the cloud auditor should verify and certify the service instance which is generally termed as attestation process.

be an issue. In different service models, the level of trust must also be different.

The goal of our research paper is to provide a concise analysis on data security and privacy protection issues pertaining to data and databases as well as the current advancement/ breakthrough made and achieved in regards to database security and privacy concerns. We will also discuss in this paper some current solutions in the security market. First, we looked at the a trusted database model which makes it possible to shield database with absolute secrecy to benefit trusted equipment presented on the side of server and made to work at the charge of any cryptography which permits private data handling on a simple device.

Abstract - Cloud Computing is huge computing, it is the internet based computing, where all users can remotely store their data into the cloud so as to enjoy the latest and high quality applications and services. In outsourcing data , users can be relieved from the burden of local maintenance and data storage .Thus, enabling public auditability for cloud data storage security is of difficult so that users can resort to an external audit party to check the integrity of outsourced data when needed. To securely introduce an effective. The following two fundamental requirements to securely introduce an effective third party auditor (TPA) .1) The third party auditing process should bring in no new vulnerabilities towards user data privacy. 2) TPA introduces no additional on-line burden to the cloud user. TPA should be able to efficiently audit the cloud data storage. 3) TPA should audit the data for checking the integrity of that data. In this we propose for privacy-preserving public auditing for cloud data storage.To enable the TPA to perform audits for multiple users simultaneously and efficiently.We also doing batch auditing for multiple users data.

The objective of this research is introducing the Trusted Computing based security mechanism to the cloud.

Usage of remote servers via internet to store, manage and process data instead of using a personal computer is known as Cloud computing. It’s a set of Information Technology services with the ability to scale up or down their service requirements. Most of the cloud services are provided by a third party service provider. In cloud computing, organizations can utilize IT services without in advance investment. Despite its benefits obtained from the cloud computing, the organizations are slow in accepting it due to security issues and challenges. Security is one of the major problems which hinder the growth of cloud. It’s not wise to handing over the important data to another company; such that clients need to be vigilant in understanding the risks of data infringement in this new environment. This paper discusses a detailed analysis of the cloud computing security issues and challenges. (Ayoleke)

Cloud Computing is huge computing utility, where user can remotely store their data into the cloud and enjoy on-demand high quality cloud application and services without the burden of local hardware and software management and also decreases the maintenance load of users by providing low cost, scalability. In the corporate world, there are a large number of clients who accessing their data and modifying data. The user can access data, use the data and store that data. Cloud computing moves the application software and databases to the centralized large data centers, where the management of data and services may not be fully dependable. To manage this data, we use TPA (third party auditor) it will check the reliability of data but it increases the data integrity risk. We propose a secure cloud storage system for privacy preserving public auditing.

Protection of data is the most important challenges in cloud computing because the location of the data is not always known. To enhance the security in cloud computing organization should provide authentication, authorization and access control for data stored in cloud. Top vulnerabilities are to be checked to ensure that data is protected from any attacks. So security test has to be done to protect data from malicious user such as Cross-site Scripting and Access Control mechanisms.

ABSTRACT: Cloud computing is a method of providing a set of shared computing resources that includes applications, computing, storage, networking, development, and deployment platforms as well as business processes. In cloud computing, data while transferring as well as storage, and get data back when it is needed there is no assurance about the security of that data stored and also it is not changed by the cloud or TPA. Therefore Security and control over data remain to play a significant role in plans for cloud computing initiatives. Existing research work earlier grant data integrity to be verified,but still there are different drawbacks, firstly basic and mostly needed authorization/authentication process is not present in between Cloud Service provider and TPA. Techniques like authentication and encryption are important, our system can provides those things for security issues. Second: in recent research POR protocol in which the verifier stores only a single cryptographic key, POR can only capable of detection of file corruption or loss, and not prevention. Maintaining the storages can be a tough task and second it requires high resource costs for the implementation. This paper, Propose a formal analysis method called full

In the world of technical life cloud computing has become integral part and also understanding the way of business is changing and is likely to continue changing into the future. Using cloud storage services means that you and others can access and share files across a range of devices and position. Files such as photos and videos can sometimes be unmanageable to email if they are too big or you have allot of data. You can upload your data to a cloud storage provider means you can speedily circulate your data with the help of cloud service and you can share your data files with anyone you choose. Since cloud computing shares distributed resources via network in the open environment thus it makes less secured. Data security has become a major issue in data sharing on cloud. The main motto behind our system is that it secures the data and generates the key for each transaction so every user can secure our shared data by the third party i.e. unethical hacker.

when we transfer data to cloud we use standard encryption tecnique to secure the data. But when we have to do computations on data stored on cloud then we have to decode data i.e provide private key every time which is not a secure method.In this paper we are introducing a technique which allow us to do computations on encrypted data which is kept on cloud on remote servers without need of any private key and without decoding it.Result of computations will be same as computations performed on raw
