Security Issues

Cloud is considered as future of Information Technology. User can utilized the cloud on pay-as-you use basis. But many organizations are stringent about the adoption of cloud computing due to their concern regarding the security of the stored data. Therefore, issues related to security of data in the cloud have become very vital. Data security involves encrypting the data and ensuring that suitable policies are imposed for sharing those data. There are several data security issues which need to be addressed. These issues are: data integrity, data intrusion, service availability, confidentiality and non-repudiation. Many schemes have been proposed for ensuring data security in cloud environment. But the existing schemes lag in fulfilling all these data security issues. In this chapter, a new Third Party Auditor based scheme has been proposed for secured storage and retrieval of client's data to and from the cloud service provider. The scheme has been analysed and compared with some of the existing schemes with respect to the security issues. From the analysis and comparison it can be observed that the proposed scheme performs better than the existing schemes.

Cloud computing, the utility base computing, is going to become the mainstream of IT future. Governments and enterprises are realizing that by immigrating into the cloud they can significantly enhance their current infrastructure or application services with minimum cost and maximum elasticity. But securing cloud user digital assets and addressing privacy concerns of cloud costumers has become serious challenge. Providing security in cloud always has to consider performance. Employing high secure methods with massive complexity will increase overall service cost, to address this problem in this paper a two- tier security architecture is proposed. This architecture use multiple work mode for security components in guest level to decrease security process over-head and a security supervisory in hypervisor layer to make sure avoiding from false security alarms

The aim of this paper is to propose a model to strengthen the security of key management in cloud computing, where the model is shared or entirely controlled by a non-trusted third party provider. Key management is not a straightforward matter for IT-teams, in addition to critical issues related to properly managing and securing the keys on providers’ infrastructures, they have to deal with concerns specific to multi-cloud key management. Hardware Security Module (HSM) solution that offers a secure on-premise encryption key management turned out be impracticable for widespread cloud deployment. HSM as a Service seems to be the best approach for key management in multi-cloud, but the service is wholly owned and managed by another cloud provider. In This paper, we present an efficient and secure cloud key management that fulfills the requirements of multi-cloud deployment. The proposed design splits the key into a blinded version of n shares that will be stored in encrypted format at the cloud provider side. To demonstrate the efficiency of the proposed design, we implement a fully featured prototype and evaluate its performance. Results analysis shows that the proposed design is highly efficient and can serve as a groundwork for using secret share as a way to protect keys in a multi-cloud environment.

Cloud computing is a platform to share the data and resources used among various organizations, but the survey shows that there is always a security threat. Security is an important aspect of cloud computing. Hence, the responsibility underlines to the cloud service providers for providing security as the quality of service. However, cloud computing has many challenges in security that have not yet been addressed well. The data accessed or shared through any devices from the cloud environment are not safe because they are likely to have various attacks like Identity Access Management (IAM), hijacking an account or a service either by internal/external intruders. The cryptography places a major role to secure the data within the cloud environment. Therefore, there is a need for standard encryption/decryption mechanism to protect the data stored in the cloud, in which key is the mandatory element. Every cloud provider has its own security mechanisms to protect the key. The client cannot trust the service provider completely in spite of the fact that, at any instant, the provider has full access to both data and key. In this paper, we have proposed a new system which can prevent the exposure of the key as well as a framework for sharing a file that will ensure security (CIA) using asymmetric key and distributing it within the cloud environment using a trusted third party. We have compared RSA with ElGamal and Paillier in our proposed framework and found RSA gives a better result.

Content-based image retrieval (CBIR) is the integrated system of the photograph fetching trouble for instance difficulty of chasing down pictures on a cloud in big datasets. To recognize request semantics and client’s needs if you want to grant submitted consequences with reference to exactness, relevance feedback is combined into CBIR shape. Important evaluation shape will manufacture the precision of yield and will pass at hugest yield. In the watermark-primarily based tradition, a singular watermark is explicitly inserted in blended photos by means of the cloud environment earlier than photos, transmitted towards inquiry mortal. In this way, when an illicit photograph reproduction is located, the illicit inquiry mortal, where appropriates can trail the pictures with the aid of the watermark extraction. Characteristics vectors get assured by using the secure hashing algorithm, analyzing and making ready age are used at image user’s aspect for confirmation motive. TPA (third party auditor) is used to understand enforcement or malevolent activities achieved in cloud circumstances. In our proposed framework, we are including the approach of misrepresentation recognition by generating trapdoor using a hashing calculation, as a document is made with the unique identifier and the client pictures with the names after the link are simplest, a trapdoor is generated.

Cloud computing is a technology where it provides software, platform, infrastructure, security and everything as a service. But this technology faces many security issues because all the data or information are stored in the hands of the third party. The cloud users unable to know where the data are store in the cloud environment and also it is very difficult to analyze the trustworthiness of the cloud service providers. In this technology providing security is a very big challenging task. This challenge was overcome by developing different cloud security algorithms using cryptographic techniques. Recently many researchers identified that if the cryptographic algorithms are combined in a hybrid manner it will increase the security in the cloud environment. Even though, many research works are still carried out to improve security in the cloud computing environment. In this research article, a new step was taken to develop a new cloud security algorithm

<strong>Currently, cloud computing is facing different types of threats whether from inside or outside its environment.  This may cause cloud to be crashed or at least unable to provide services to the requests made by clients. In this paper, a new technique is proposed to make sure that the new node which asks to join the cloud is not composing a threat on the cloud environment. Our new technique checks the node before it will be guaranteed to join the cloud whether it runs malwares or software that could be used to launch an attack. In this way the cloud will allow only the clean node to join it, eliminating the risk of some types of threats that could be caused by infected nodes.</strong>
