Introduction In the current era of digital world, various organizations produce a large amount of sensitive data including personal information, electronic health records, and financial data. It is difficult for local system to manage such large data because it requires more storage space and skilled staffs. So it becomes very expensive for any organizations. capable personnel. Therefore, storage-as-a-service (Saas) offered by cloud service providers (CSPs) give better solution to store large sensitive data, therefore maintenance cost reduced much more by means of outsourcing data storage. Since the data holder actually releases sensitive data to a remote CSP, there are some concern regarding privacy, honesty, and access control of the data. The privacy of user can be achieved by data holder using encryption before storing data to remote servers. To achieve data honesty over cloud, analyst has proposed provable, information ownership procedure to accept information storage on remote destinations. Various PDP conventions have been exhibited to proficiently accept the respectability of information. Generally, conventional access control procedures accept the presence of the information holder and the capacity servers in the same trust space. This opinion, no more useful when the information are outsourced to a remote CSP, which takes the full charge of the outsourced information administration, and lives outside the trust area of the information holder. The
User can store their data on cloud and reveal from the local data storage and its maintenance. Cloud is in a distributive in nature includes shared pool of configuring resources both in hardware and software. As an increasing number of clients who store their
Cloud solution provides shared resources on demand, which is highly configured and computed, with minimized management efforts required. With the emergent of cloud services, individual users and enterprises with various capabilities would able to manage their data either locally or remotely, with servers located somewhere else, or they pay to have cloud providers manage the data.
Several researchers have addressed the issue of depending on a single cloud storage service, such as cite {AbuLibdeh2010} cite {Scalia}, and they believe that adopting multiple cloud storage services is a useful approach to tackling the problems associated with the dependence on a single cloud provider. Simply, This method combines several independent cloud services and considers them as one cloud. Although the distribution of data among several cloud storage services increase availability, performance, and reduces the probability of losing data, it may increase the amount of storage and bandwidth used and as a result, the cost rises. Scalia cite {Scalia} introduced a cloud brokerage solution that continuously adapts the placement of data, based on files access statistics among several cloud storage services to minimise the storage cost, improve the data availability, and eliminate vendor lock-in risk. However, The work does not evaluate the impact of the system on the latency time. HAIL cite {Bowers2009} used the principle of RAID to distribute files across a collection of cloud storage to enhance the availability of data and remotely manage data security risks (i.e. data integrity) in the cloud by employing the Proofs of Retrievability (PORs) system. Although this work shows a reduce in storage cost, they do not consider the effect of access patterns on the network cost. Besides, they assume that
The main driving forces of cloud data storage are reputable companies such as Amazon and Google building comprehensive computing infrastructures (Google, 2009). These infrastructures are removing the complexity of in-house data storage and ultimately reducing costs of limited networked data centres (Hitachi, 2010). The traditional inefficient model of purchasing servers every time you need to accommodate for high use or growth is now being replaced by internet based systems that replicate your data centres but without the big overheads (Google, 2009). This flexibility assists in the ever changing business world and its continuous improvement initiatives to remove waste, improve efficiency, and ultimately reduce costs. Another key driving
Therefore a model should be developed to promote CIA. By encrypting data, scheduled back up and access control, CIA can be provided.
The impacts of cloud computing have touched almost every area of Information Technology. The information kept in the cloud is private and confidential and protected by laws that regulate it and protect it. The cloud providers face laws that relate to the preservation of critical information touching on taxes, security, and sometime employment regulations. Also in other circumstances, they are forced to comply with laws requiring them to destroy such information.
Although cloud computing was first introduced in 1950’s, it’s importance of storing digital files online and providing access to it everywhere has become particularly evident over the last decade. Cloud computing can provide access to many daily life services, such as banking, educational and business through the use of mobile phones. Cloud computing solves many daily problems and makes sharing any type of data much easier. Cloud computing shares data through Internet, which makes it easier for anyone to have access to data. Although cloud computing has many advantages, there are also many disadvantages. Many businesses uses cloud computing to get access to various types of data that would benefit them in
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)
Cloud Computing is huge computing utility, where user can remotely store their data into the cloud and enjoy on-demand high quality cloud application and services without the burden of local hardware and software management and also decreases the maintenance load of users by providing low cost, scalability. In the corporate world, there are a large number of clients who accessing their data and modifying data. The user can access data, use the data and store that data. Cloud computing moves the application software and databases to the centralized large data centers, where the management of data and services may not be fully dependable. To manage this data, we use TPA (third party auditor) it will check the reliability of data but it increases the data integrity risk. We propose a secure cloud storage system for privacy preserving public auditing.
Cloud Computing appears as a computational paradigm as well as distribution architecture and its main objective is to Provide secure, quick, convenient data storage and net computing device, with all computing resource visu-alized as service ,with all computing resources visualized as service and delivery over the internet [1,2].The cloud enhances collaboration, agility, scalability, availability, ability to adapt to fluctuations according to demand, accelerate development work, and provides potential for cost reduction through optimized and efficient compu-ting [3,5].Cloud computing is buzz word of IT industry today and present everywhere and every one's mind. Cloud computing is ubiquitous, next generation's infor-mation technology architecture which offers on-demand access to the network. It is dynamic, virtualized, scalable and pay per use model over internet. Cloud computing is a box of several concepts such as virtualization, Service oriented architecture (SOA), web 2.0 and many more. In some respects, Cloud Computing represents the maturing of these technologies and is a marketing term to repre-sent that maturity and the services they provide [4].There are several advantages of adopting cloud computing but still journey of cloud is not easy. Cloud still is its early stage, suffering from many pitfalls and one of the most concern is security along with availability, privacy and compliance. Traditional security mechanism such as Authentication , authorization ,
Due to increased activity around ransomware, cyber threats, and impactful critical incidents, a review of the Backup Process within Storage Management was requested. There is some concern that bank-critical applications and services, may be exposed to increased risk, impact, and unavailability if backups are not available in a time of need. The goal of this investigation is to review the existing process and identify areas for improvement.
Abstract—Here in this paper a new and efficient technique for the Sharing of Data over Cloud Computing is proposed. The proposed Methodology implemented here is based on the concept of implementing Hard Logarithmic based Problem such as Elliptic Curves Cryptography. The Proposed Methodology Works in Two Phases : First Key generation using Hyper Elliptic Curve and Second by Encryption the Shared Data using these keys and Encrypted using Cipher Text Policy based Encryption. The Proposed Methodology provides Security from various Attacks and also reduces Computational Time and Cost as compared to the existing methodology.
We proposed new provable data possession which provide outsourcing of multiple copies of dynamic data, where data owner is suitable of not only archive and access data copies keep by cloud service provider but also modify and scale those copies on server. To principle of our understanding, this scheme is to address multiple copies of dynamic data. The communication between authorized user and cloud service provider is taking into account, where authorized user can access data copy accept from CSP using separate key distribute with data owner. It maintains the feature of determining indices of corrupted copies. The corrupted copies can be recreate from entire damage applying duplicate copies on different
In this work I am proposing to design framework based on trusted computing technology to improve data security and confidentiality in the cloud. In order to do that I will work on defining protocols to make sure that data storage and replication is only done on trusted storage servers and also data access from the cloud is secure for the client and users. Cloud computing allows clients to use computing resources with option of pay per use. It is convenient option used widely in Information Technology industry. Data security and confidentiality is problematic when data transfers to third party.
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
