Abstract:
Cloud computing is an emerging technology in modern society. In recent years mobile users and cloud service providers are increased rapidly. In the cloud or any other distributed environment, if the users increased then security risks also increase parallelly. Many security problems are still unclear even after the advanced security measures have been taken. Security of stored data in the server is one of the most challenging issues in the cloud-based environment. Only authorized users should access the stored data of the server. Authentication plays a significant role in providing authorization. Therefore, in cloud computing, authentication is the primary measure to protect the data and the server from an unauthorized user. In this paper, an efficient authentication scheme using the smart card in the cloud environment is proposed. In the proposed scheme, with the help of a single private key, the user can access many cloud services. Also, the proposed scheme resists all security attacks. Through the simulation using the AVISPA tool, it is proved that the proposed scheme is robust and suitable for practical implementation.Cloud computing is setting off great changes in the IT industry. There are more and more researches on cloud computing. And this paper focuses on cloud computing too. At the beginning this paper describes the characteristics and definitions of cloud computing, and then introduced its services patterns (including SaaS, PaaS and IaaS) and deployment patterns(including public cloud, private cloud and hybrid cloud), at the end lists the cloud security challenges that cloud computing faces.

A hybrid cloud system basically mixes on-premises and cloud computing resources to provide workload distribution, security, and mobility. A hybrid cloud might contain two or more personal clouds, or it could have one public cloud and one private cloud, depending on what is needed. Typically, third-party providers like Microsoft, Google, and Amazon offer cloud services to the public. The primary goal of cloud computing, which is an innovative approach, is to provide net computation and safe, rapid, and easy data storage. Security concerns are crucial even if cloud computing significantly lowers the cost and upkeep of the IT sector. Security concerns are crucial even if cloud computing significantly lowers the cost and upkeep of the IT sector. Cloud-based services including private, public, and hybrid cloud computing are being used by an increasing number of IT firms. However, they are also worried about security-related issues. Private, public, and hybrid cloud computing challenges are covered in great detail in this article. As more businesses use cloud services and architectures in the modern business world, additional dangers and concerns surfaces.

In recent years, cloud computing had a great impact on technology. Cloud computing has formed a conceptual and infrastructural basis for future computing. It provides services like Software as a Service, Platform as a Service and Infrastructure as a Service which can be deployed on / by private cloud, public cloud, community cloud or hybrid cloud. With the number of advantages of this technology, it comes with various challenges and issues simultaneously. From the challenges, security is considered the most critical one as the data is stored on the remote locations with the help of the Internet instead of using hard disks. This paper firstly discusses the basics of cloud computing, its service models and deployment model and then focuses on cloud security and issues related to it.

ABSTRACT
In computerÂs world these days cloud computing plays very important role. It gives user facilities like group of
things such as software, platform and infrastructure services. Virtualization is the backbone of cloud resource
sharing. Security is also a main problem of cloud. Multiple users have their own perception related to the cloud. By
making use of cloud computing techniques the user is easily able to use to resources anywhere by using internet. So
this technique is very useful in userÂs daily life. One of the factors for cloud computing is cloud services which were
provided by the cloud (IAAS, PAAS, and SAAS). These services enable users to access infrastructure, platform and
software. Even resources are allocated to users according to their requirements. But many people think that using
cloud resources and its services is not safe because there is no guarantee of information which is controlled or
maintained by the vendors. There are some security issues which are usually experienced while using the techniques
of cloud computing. The present research presents an overall investigation data security, protection and issues in the
cloud. The paper also defines the literature review related to the cloud computing issues and treats. Various security
concerns are also discussed in this paper.

Cloud Computing is a cropping technology. There are many researches going under this cloud technology. There are many challenges in terms of security for data stored in cloud. Currently there are four cloud deployment models named as public cloud, private cloud, community cloud and hybrid cloud available in the market. According to the requirements customers can avail one among the four available cloud models. This paper especially discusses the security problems and stinks occurs for hybrid cloud. This paper also analyzes various factors that effects the security of the information stored in cloud. It provides a better understanding of the cloud computing research challenges, open issues and helps to find top security threats and solutions in hybrid cloud.

It is unsafe to use cloud because there is no guarantee of information which is controlled or maintained by the vendors. There are some security issues that are noticed in cloud computing. In this paper, we have discussed a few issues with cloud computing and the challenges of cloud computing. This paper gives overall investigation of security on data, protection and issues in the cloud. The paper also defines the literature review related to the cloud computing issues and threats and also the various security concerns are discussed.

Cloud computing is one of the widely used technology in the 20th century. Cloud has become an essential part in our day-to-day life, because the data are stored in the cloud in any one form such as Gmail, Google Drive etc. As the users store sensitive information in the cloud, the Cloud Service Providers need to provide proper data security for data stored in the cloud. There are many issues in Cloud Computing Security. This paper discussed about various issues in the Cloud Computing environment and the future work directions have identified for the Cloud Computing Security.
