Introduction In recent years two technologies have combined synergistically, the cloud and mobile. Organizations rely on the existence of powerful cloud-based syncing and storage technology to provide a compelling cross-platform user experience. The need to overinvest in infrastructure is eliminated as companies look for solutions that provide scalable, affordable and specific answers to frequent questions. With so much data flowing, the cloud is the only technology suitable for filtering, analyzing, storing, and accessing that information in useful ways. The challenge of a cloud based solution lies in the seemingly unverifiable security offered by the given provider. While the provider assures data protection and offers specific methods, verification of its effectiveness poses obstacles due to the nature of the cloud being a shared resource. Auditing procedures are hard to satisfy, as the provider will only allow the audit to go so far before citing a conflict of interest with other clients. Quietly companies are beginning to see how little control they have over data stored in the cloud. Data encryption is one method to exert some control. Today these measures are meant largely to protect data traveling between customer companies and cloud service providers. What is needed is a zero trust security model and homomorphic encryption is potentially the key to that future. Our paper considers the possibility of homomorphic encryption as a viable defense against the data

Organizations use the Cloud in a variety of different service models (SaaS, PaaS, IaaS) and deployment models (Private, Public, Hybrid). There are a number of security issues/concerns associated with cloud computing but these issues fall into two broad categories: Security issues faced by cloud providers (organizations providing software-, platform-, or infrastructure-as-a-service via the cloud) and security issues faced by their customers.In most cases, the provider must ensure that their infrastructure is secure and that their clients’ data and applications are protected while the customer must ensure that the provider has taken the proper security measures to protect their information.
Cloud computing has set a trend in the information technology arena that has sparked the interest of all who utilize the internet on purpose and unsuspectingly. Initially, the primary purpose of cloud computing was to provide a centralized data bank that organizations could use for quick data access. Its use has been quickly adapted, however, beyond business use to become the first option for personal use. The advantages and disadvantages of implementing such a shift from business to personal are varied, yet, statistically, according to the CISCO Global Cloud Index: Forecast and Methodology, 2014-2019 White Paper, its public use is on the rise. The report notes that “by 2019, 56 percent of the cloud workloads will be in public cloud data centers, up from 30 percent in 2014 and by 2019, 44 percent of the cloud workloads will be in private cloud data centers, down from 70 percent in 2014”. Though disadvantages with regard to data security is prominent, users have deemed that its implementation will still promote greater benefits than loss.
This research paper tackles the issues that faces Cloud Computing today and gives the experts and industry’s point of view on the matter. The aspects explored are the significant industry questions that have risen about the use of Cloud Computing, business value, organization impact, adaptability, limitations, initial cost of implementation, and the severe business security risks
The first scenario that will be examined is looking at Cloud Computing from the perspective of security. Many small and medium sized businesses utilize the internet and Cloud Computing to conduct business and transfer money from system to system as well as report on financial accounting data. With that being the case, it is crucial that whatever system the business is working with pays very close attention to security needs to ensure that this data is protected from unauthorized sources viewing or manipulating it.
Ten years ago business professionals were grappling with the decision of whether to implement cloud computing into their organizations. Today, we no longer have the luxury of “If” we will embrace the new technology but rather “How” we will make it as safe as possible.
In the present world, almost everyone is connected through internet to access anything via a single click. Some may prefer Facebook as their socializing media whereas others may use Twitter or LinkedIn. Similarly, some use Gmail account whereas others prefer Hotmail or Yahoo. All these can be accessed from anywhere in the world via any device such as laptop, smartphone, etc. There is no restriction to use it only from a specific device or using a specific network.
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.
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)
The second approach in dealing with the major cloud computing challenges for enterprises is the provision of comprehensive implementation guidelines. These guidelines are geared towards addressing the challenge of service quality, integration issues, and to enhance the real benefits from the implementation of cloud computing applications. Some of the major guidelines or steps to consider include understanding the cloud application, demand transparency, consider legal implications, and reinforce internal security. Enterprises should strive to understand how cloud computing applications transmit and handle data by realizing the impact of the application’s loose structure on security of data transmitted on it. These enterprises should also ensure that cloud providers supply comprehensive information regarding its security architecture and is ready to accept periodic security audit. In addition to knowing the laws and regulations that affect data transmission on the cloud, enterprises should also enhance internal security measures through user access controls and use of firewalls.
Corporations are finding the value from moving their enterprise systems from on premises to the cloud. There are several reasons for companies to do this; professionals need to be engaged in activities that will drive the company’s business instead of keeping hardware running. Lipsitz (2011), Cloud service providers can provide business ready alternatives more securely, efficiently, and at a better price. IT organizations should be investigating those alternatives and redeploying IT staff to more business critical projects. The concept of anytime, anywhere on any device is no longer a concept, it is a necessity. Many enterprises have employees that work remotely, are mobile and need to get their information on many different devices. The cloud has the correct architecture to deliver services to employees while keeping them productive and enabling them to collaborate on the move. Cloud services also provide scale to allow businesses to resize their services when needed.
By adopting the Mobile Cloud computing paradigm some research work has been done to address some of the key features of the cloud databases and mobile databases. There are two important features where data management needs to be taken care of:
First, when computers or PCs were introduced, they literally took the space of the whole room. They were heavy and bulky but still had many limitations in terms of what can those PC actually do or perform daily human tasks. As PCs have evolved, the new software’s have also evolved. A software that satisfies the needs of sending secure data over the Internet is called cloud computing. With PCs, cloud computing has evolved to another level making it easier and simpler to use and provide others with secure information. One problem that is faced by cloud computing organization is the doubt of it keeping files secured. Security reasons are the main concern for cloud computing since everything is over the Internet. On the other
This paper proposes, various methods for anonymous authentication for data stored in cloud. Cloud verifies the authenticity of the series without knowing the user’s identity before storing data. This paper also has the added feature of access control in which only valid users are able to decrypt the stored information. These schemes also prevents replay attacks and supports creation, modification, and reading data stored in the cloud. Moreover, our authentication and access control scheme is decentralized and robust, unlike other access control schemes designed for clouds which are centralized. The communication, computation, and storage overheads are comparable to centralized approaches .The aim of this paper is to cover many security issues arises in cloud computing and different schemes to prevent security risks in cloud.
Introduction: With the latest developments in the area of could based computing have completely transformed the way of computing and the resources of computing. In the environment of cloud computing, the various resources are frequently present in a network of someone else and accessed by the cloud based users remotely. Processing is completed remotely. The data need to be transmitted from a person to server or the cloud based infrastructure for processing and the output is returned when required processing finished. Security is an important aspect of safer computing . In today’s world it is easy for unwanted guests to enter into any private computer by using different types of hacking. There are so
Going to the cloud does not mean relinquishing security control or accepting a security posture that is less secure for cloud-hosted workloads relative to premised ones. In fact, the selection of cloud provider can mean having access to the very latest in security technologies, even more granular control and faster response than is possible with security in traditional networks. As a first step, security stakeholders need to understand how sensitive and compliance intense their cloud-hosted workloads and data are. They should then opt for access controls that limit use to
