Unit 2.5 Assignment 1

A company allows its staffs in the same groupor department to store and share files in the cloud. By utilizing the cloud, the staffs can be completely released from the troublesome local data storage and maintenance.However, it also poses a significant risk to the confidentialityof those stored files. Specifically, the cloud serversmanaged by cloud providers are not fully trusted by userswhile the data files stored in the cloud may be sensitive andconfidential, such as business plans. To preserve dataprivacy, a basic solution is to encrypt data files, and thenupload the encrypted data into the cloud. Unfortunately,designing an efficient and secure data sharing scheme forgroups in the cloud is not an easy task due to the followingchallenging issues.First, identity privacy is one of the most significantobstacles for the wide

Recent technological advancements have resulted in an increased number of Internet-enabled devices, such as tablets and smartphones that can connect to corporate systems.These systems may also be running anywhere, including a public software-as-a-service (SaaS) cloud, a

Imagine massive server failures that not only lead to complete data loss, but also a financial crisis for customers. This is the problem that Lloyds Banking Group faced when servers failed and left thousands of customers without access to their accounts according to Clarke (2014). In order to protect firm data, firm reputation, and especially customer trust and loyalty, Bank of America needs to assure proper precautions are taken to securely store all data.

The National Institute of Standards and Technology (NIST) define cloud computing this way. “Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics (On-demand self-service, Broad network access, Resource pooling, Rapid elasticity, Measured Service); three service models (Cloud Software as a Service (SaaS),

ABSTRACT: A Distributed computing is a rising figuring innovation. It allows clients; store their information, learning or data remotely. The reason for this paper is to secure access control plan for open mists. We display a "Security Preserving Two Layer Encryption Access control in Public Clouds", which gives more security and protection as contrast with the custom approaches. Current ways to deal with uphold access administration polices (ACPs) on outsourced information utilizing chose encryption oblige associations to deals with all keys and encryptions and transfer encoded information on the remote stockpiling. Such kind of methodologies brings about high correspondences and the reckoning expense to oversee keys and encryptions at whatever point client roll out improvements. To delegating so as to take care of this issue as a significant part of the Access Control authorization obligations as conceivable to the cloud while diminishing the data presentation hazard because of intriguing clients and Cloud.

Security is typically ranked the top cloud computing adoption concern. Many feel that cloud is not yet a secure enough option for storing and processing mission critical or customer-sensitive data, and may never be. So it’s important to evaluate security solutions provided by various vendors to see what data protection you will be receiving from a specific cloud vendor for your mission critical and sensitive data. Comparison of security solutions provided by four well known cloud service providers is listed as below.

However, with the convenience of cloud storage come real risks. Cloud storage is quite attractive, given the advantages previously stated, but there are still great concerns, including reliability and security. Organizations relying on cloud computing must ensure that the third party they’ve entrusted to store their data can guarantee that they can access their information at any time and that their information is safe from the threat of hackers (Berman, 2008, p. ).

1.one task will put your information in an iron box of secure equipment, enabling clients to run refined interchanges in the cloud while keeping their "key" and information mystery even from the cloud provider.

(REWRIET) “EaaS speaks to a cloud-driven way to deal with security, where the capacities of a solitary specialist co-op can be utilized to encode information on many cloud stages and gadgets, whenever, from any area, safely. Permits cloud benefit clients to exploit the security that encryption offers without installing and utilize encryption all alone. Cloud encryption is practically indistinguishable to in-house encryption with one vital contrast, the cloud client must set aside opportunity to find out about the supplier's approaches and strategies for encryption and encryption key administration. The

Storing important data safe and accessible from different locations has become a global preoccupation, either being this data personal, organizational or from applications. As a consequence of this problem, I suggest the emergence of on-line storage services. In addition, there

The cloud computing has helped organizations better use IT resources to increase flexibility and performance. But operating system which is based on cloud computing may have users connected to it on a scale of thousands via network. To accomplish to this scale there are issues that need to be tended to. A user may move data from cloud supporting to non-cloud environment and vice versa, so it is important that operating system supporting cloud computing has interoperable data processing. There is no global cryptography standardization for cloud based environment which makes it vulnerable to various security threats. Operating

Quality based access control is given to make the client to get its own particular information fields as it were. Proxy re-encryption is used to give a way to deal with sharing of information between number of clients. In this work, the Key aggregation with random key generation is utilized to combine keys if there is more than one key is produced to one file hat is partaken in the cloud. It conceals the base encryption file from the end client. The Honey encryption method is utilized to improve the proxy re-encryption cryptosystem. This proposed work will be captivating multi-client contrive of cloud applications.

Having a physical storage device is no longer a necessity; for many users, cloud storage provides a cost effective solution to store as much data as needed and enables the flexibility of accessing data from anywhere. Cloud storage is the best method for keeping up with the rising storage demand and reduces the risk of losing data in the event a local system fails. Nonetheless, cloud storage has led to several security issues for users, it presents the risk of not having full control over the stored data as it is physically outside the control users. Cryptography is the main mechanism in cryptographic access control; cloud storage providers should ensure cryptographic access control for the security of stored data.

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

Cloud computing is one of the most popular Technology In terms of Data storage and sharing remotely. In my research proposal, I will examine some of the security challenges while using hybrid cloud in Information Technology and how to overcome these security issues by using different key management techniques. In this research proposal I will explain implication of key management mechanisms and how to overcome security problems in Hybrid cloud computing by using key management mechanisms. In
