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):

security of the cloud computing system. As stated in Gwu.edu. (2010), “We must be able to

A significant paradigm shift is represented by public cloud computing from conventional norms of an organizational data center to a de-parameterized infrastructure which opens gates for potential adversaries to use. Cloud computing should be approached carefully with any emerging information technology area with due consideration to the sensitivity of data. A good planning helps and ensures that the computing environment is secure to the most possible extant and is in compliance with all relevant policies of an organization and makes sure the privacy is maintained.

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.

DATA SECURITY IN CLOUD COMPUTING Introduction: Cloud computing has prompted a movement in how individuals consider IT frameworks structural engineering. Numerous associations today are either executing cloud-based services, or assessing which cloud-based measures they will be portraying later on. As indicated by Gartner Inc. distributed computing is "no less compelling than e-business". This sprocess in building design from an undertaking normal server-based framework to a cloud-based framework will have related expenses of passage and dangers, yet it can bring about inconceivable advantages in reserve funds and in IT and business deftness.

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.

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. The management of data, services may not be fully dependable when cloud moves the application software and databases to the centralized data centers and those data center is large. In this we propose a privacy-preserving public auditing for cloud data storage. To enable the TPA to perform audits for multiple users simultaneously and efficiently. And also doing batch auditing for multiple users ' data.

From the viewpoint of data security, which has always been an important form of quality of service, Cloud computing surely poses new challenging security threats for number of reasons. Firstly, traditional cryptographic primitives for the purpose of data security protection cannot be straight accepted due to users loss control of data under cloud computing. Therefore, verification of correct data storage in the cloud must be attended without accurate knowledge of the whole data. Considering different kind of data for every user stored in the cloud and the requirement of long term continuous security of their data safety, the problem of checking correctness of data storage in the cloud becomes even more challenging.[1]

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)

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

Cloud computing is a virtual pool of resources and it provides these resources to users via internet. But it comes with few problems like data privacy, security and reliability etc. The most important problem in all these is security and privacy. Securing the cloud means protecting the databases. We are going to discuss about different security issues occurred in cloud and different cryptographic algorithms which are used to provide security. Due to cloud computing even though the user has minimum hardware requirement, the user can use the maximum capability of computing.

Having a physical storage device is no longer a necessity; for many users, cloud storage provides a cost effective solution to store as much data as needed and enables the flexibility of accessing data from anywhere. Cloud storage is the best method for keeping up with the rising storage demand and reduces the risk of losing data in the event a local system fails. Nonetheless, cloud storage has led to several security issues for users, it presents the risk of not having full control over the stored data as it is physically outside the control users. Cryptography is the main mechanism in cryptographic access control; cloud storage providers should ensure cryptographic access control for the security of stored data.

In this we discuss first about the no of pressing security challenges in Cloud Computing and outsourcing security, secure computation outsourcing challenges The we will focus on the primitive services, storing of data in the cloud by giving access to the owner outsourcing there data to cloud for getting the further benefits. The owner no longer having physical possession of the outsourced data raises on the storage correctness by big security concerns. So providing the access for the secure storage auditing in the cloud environment with this new approaches challenging, impressive and we can store the data by outsourcing security in the cloud computing and we

In order to overcome the security problems faced by cloud computing a new technology known as Homomorphic encryption is being put to use. It is a type of encryption that allows all the computational process to be made available to carry on cryptographic which is one on a plain text using an algorithm. This is one of the most improved and effective technique used in today’s architecture that is related to communication systems. This encryption combined all the different services that are needed together without letting out the data to any of these services. This homomorphic encryption data can be transferred into cryptographic encryption by altering the design. This change allows their encryption to be used in cloud computing
