Cloud computing is an internet based computing which enables sharing of services. Cloud computing allows users to use applications without installation any application and access their personal files and application at any computer with internet or intranet access. Many users place their data in the cloud, so correctness of data and security is a prime concern. Cloud Computing is technology for next generation Information and Software enabled work that is capable of changing the software working environment. It is interconnecting the large-scalecomputing resources to effectively integrate, and to computing resources as a service to users. To ensure the correctness of data, we consider the task of allowing a third party auditor (TPA), on behalf of the cloud client, to verify the integrity of the data stored in the cloud, the auditing process should bring in no new vulnerabilities towards user data privacy, and introduce no additional online burden to user. In this research paper, we ...
HLA Based Third Party Auditing For Secure Cloud Storage
2014
Using Cloud Storage, users can remotely store their data and enjoy high quality applications and services from a shared pool of resources. However, users, when they don’t have the physical possession of the data, chances of raising data integrity issue are possible. Thus, verification of data integrity is the at most important for a user, who has outsourced data to the cloud. To make the integrity check, a public auditing must be made possible. For it, we resort to a Third Party Auditor (TPA). Also, the auditing process should not bring in further more burdens to the user. In this paper, we propose a secure cloud storage for which we integrate the technique of Homomorphic linear authenticator with random masking. Thereby, we can assure integrity of the user’s outsourced data in the cloud.

It allows user to use application without installation of any application and user can access their personal files and application at any computer with internet or intranet access. In recent time number of user are using clouds for storing their data on cloud. It is beneficial for user because it allows user to store data and user can access it anytime and anywhere. Cloud computing is the technology for next generation information and software enabled work that is capable of changing software working environment. Cloud computing is the connection of nodes here nodes are computers connecting with each other for sharing information. The cloud is a platform where data owner remotely store their data in cloud storage. The main goal of cloud computing concept is to protect and secure the data which come under the property of users. The security of cloud computing environment is exclusive research area which requires further development from both research and academic communities. In the corporate world there are a huge number of cloud users which is storing data on cloud, accessing the data and modifying the data. In the cloud, services and application move to centralized huge data center and services and management of this data may not be trustworthy, into cloud environment the computing resources are under control of service provider and the third-party-auditor ensures the data integrity over out sourced data. As users are placing their data in cloud so correctness of data and security is the prime concern. Cloud data security is a major concern for the cloud user while using the cloud services provided by the service provider. To ensure correctness of data here we propose the task of allowing a third party auditor. On behalf of cloud user request to verify the integrity of data stored in the cloud is done by TPA .The advantage of TPA is that there is no additional online burden to user.In this paper we propose a secure cloud storage system supporting a privacy preserving public auditing. We further extend our result to enable the TPA to perform audits for multiple users simultaneously and efficiently with AES and BLOWFISH Encryption Algorithm. This shows the proposed scheme is highly efficient and data modification attack, and even server colluding attacks. Resulted encrypted method is secure and easy to use.
A Comprehensive Survey on Public Auditing for Secure Cloud Storage
International Journal of Engineering & Technology
Cloud computing is the most popular paradigms used today by Industries & individual users to store data. This outsourcing releases user from capital as well as maintenance cost to own their data. But it brings new security challenges such as data integrity & privacy since user has no power of control on his own data. Advances in encryption & authentication techniques has improved security of data at cloud server(CS) but still it is not providing any certificate or assurance about cloud data to user. Most of the times users are not aware of the different controls employed by CS to protect integrity of data. Due to this lack of transparency in system, the user may lose trust on CS. Hence it is a need of user to check integrity of his data at regular intervals. Most of the researchers have given solutions to this problem with the help of cryptography techniques. External parties such as Third-Party Auditors (TPA) are performing audit to verify this remote data on behalf of user. This p...
Implementation of Public Auditing for Privacy Preserving in Secure Cloud Storage
Cloud computing area provides solution to the problem of limited storage using which a user can remotely store his or her data and enjoy the on demand high quality applications and services from a shared pool of configurable computing resources without handling the burden of local data that is being stored and maintained but the major fact is a user no longer possess the outsourced data that makes the data integrity protection in cloud computing environment as a formidable task for the users who posses constrained computing resources which pretends to use the cloud storage as if it is local without worrying about the need to verifying the data integrity by enabling public audit ability for cloud storage as it is considered to be critical where a user can resort to a third party auditor (TPA) to check the integrity of the outsourced data and be worry free. The vulnerabilities toward user data privacy introduce no additional online burden to user and in this paper we propose a secure cloud storage system that supports privacy preserving public auditing technique which is further extended to perform audits for multiple users simultaneously and efficiently by implementing extensive security and performance analysis which is proved in the proposed scheme which is provably secure and highly efficient.
Reliable and Enhanced Third Party Auditing in Cloud Server Data Storage
International Journal of Security and Its Applications, 2017
Cloud computing provides a service based environment for data storage and resource sharing that are available to user through internet with on-demand basis. Thus, users can access their data across any geographical location at any time. Cloud environment also provides better scalability, flexibility, high performance, availability and less storage cost as compared to other physical storage of data. Maintaining data integrity and security in cloud environment is difficult especially, when the stored data is not completely reliable and trustworthy. However, the security of stored data is the major concerned for organizations and individual user to adopt cloud based environment. In this paper, we have proposed and enhanced the functionalities of third party auditor server to protect the availability and integrity of outsourced data in a cloud environment. The proposed approach uses the functionality such as, public verifiability, metadata generation, data dynamics, storage access point, encryption and decryption of data through RSA algorithm and IP range in case of private cloud. The proposed work also focuses on a solution to reliability, availability and integrity of data that are the major issues in the cloud adoption.

Using cloud services, anyone can remotely store their data and can have the on-demand high quality applications and services from a shared pool of computing resources, without the burden of local data storage and maintenance. Cloud is a commonplace for storing data as well as sharing of that data. However, preserving the privacy and maintaining integrity of data during public auditing remains to be an open challenge. In this paper, we introducing a third party auditor (TPA), which will keep track of all the files along with their integrity. The task of TPA is to verify the data, so that the user will be worry-free. Verification of data is done on the aggregate authenticators sent by the user and Cloud Service Provider (CSP). For this, we propose a secure cloud storage system which supports privacy-preserving public auditing and blockless data verification over the cloud.
Public Auditing for Secure and Efficient Cloud Data Storage: A Comprehensive Survey
IJARIIE, 2021
Nowadays storage of data is big problem because the huge generation of multimedia data likes images, audio, video etc. whose size is very large. For storing of these data size of conventional storage is not sufficient so we need remote storage such as cloud which is resilient infrastructure, reliable and high quality performance for the cloud users. In the cloud there is no direct physical control over the records because the cloud uses its resource pool for storing. Consequently data reliability fortification and auditing is not a modest task. The user prerequisites to depend on a Third Party Auditor (TPA) who is working as a public auditor for authenticating the data integrity and privacy. This paper presents the various auditing techniques of cloud computing for improving security and then future research challenges which need to be adopt by researchers to make system obvious.
