Encryption and spatial encryption performance and average response time have been estimated based on the size of the data file. RSA encryption is often used in cloud storage. It allows cloud services to search encrypted data directly. Cloud Server provides storage and search services. To perform efficient searches, the cloud uses verification keys to maintain privacy protection or meet authentication requirements and provide equivalent proof of encrypted documents based on tokens. Most security issues are caused by people deliberately creating malicious or malicious purposes. This Paper reviews and examines some Encryption and Decryption technologies. As a result, the better solution to the symmetric key encryption and the asymmetric key encryption is provided. I INTRODUCTION Cloud computing is a distributed community that provides calculating or storage space as services to end users. The architecture / model of cloud computing is that all servers, networks, presentations or other basics connected to the facts centre are accessible to the end users. Cloud computing is upward in attention of technology and business organizations, but this is useful for solving social problems. It can also be beneficial. Cloud computing refers to online operation, configuration and access to applications. It provides online data storage, infrastructure or submissions. Cloud computing allows individuals and businesses to shift the burden by managing large amounts of data or performance processes that require computing for powerful servers. Due to the growing approval of cloud figuring, more or more data proprietors are being encouraged to subcontract their data to cloud attendants in order to provide great convenience and reduce data management costs. Data tenants provide services to many businesses and companies, and they insist on improving data security standards by following a covered method, including following: data encryption, key organization, strong admission controls, or security intellect. The cloud attendant performs query or returns encrypted papers with an additional proof according to the token generated by Data owners. The Data users will receive the result with the corresponding proof so they can verify the correctness and decrypt scrambled leaflets after verification is accurate. Concepts Of Cloud Computing-Cloud computing is an advantage of information technology / business applications. Any organization can gain this benefit by paying or renting usage. Storage, servers and applications belong to the cloud computing area and are prerequisites for on-demand access. Therefore, unlike traditional methods of building data centers, hardware, applications and applications can be executed in a secure way before concentrating on building / transmitting business solutions. Cloud computing eliminates the need for expensive data centers and management because cloud vendors provide, manage and monitor the health and accessibility of the framework. Registering a cloud is an event on the network that allows administrators to provide versatility, quality of service (QoS) and, in most cases, to ensure custom on-demand and low-cost computing infrastructure. These infrastructures can be simple and access in a universal way. Cloud computing is a model used to authorize expedient, on-demand network admission to a public pool of configurable computing value (such as systems, servers, storage, function, or management). These resources can be managed by negligible or cloud Service-fast configuration and release The term "cloud" for vendor interaction is built from the network and its schematic representation is cloud. It refers to various specific types of services or submission that have been communicated in Internet cloud, and in many cases the devices used to get these products and applications require no special applications. Cloud Architecture-The rise of cloud computing is rapidly changing business and innovative ideas and having different effects on different individuals. For utilities and IT customers, IT management (ITaaS)-that is, computing, storage and applications is transferred from the central data centre via the Internet. For Internet and software developers, this is the stage of development of web-scale programming. Operating environment For infrastructure providers and administrators, it is a huge distributed data centre infrastructure that is connected to IP networks. Top layer (application layer): The top application that is delivered as needed according to the software as a service model (SaaS).

For secure cloud storage the process of encryption of the data to the users for various needs has been brought by the delegated access control method. Generally storage in public cloud requires high communication, heavy load due to maximum storage and high computational costs. In this paper, we are implementing multi-cloud environment for secure storage where it acts as a public cloud and provides low costs, also it involves two-layer encryption over the data stored in the cloud. We are using an efficient AES algorithm which provides higher confidentiality and privacy for several users in the cloud and stores the data in multi-clouds where the users can retrieve with the keys later while delegating it through access control from the cloud[1]. Security as well as expenses are the peak issues in this field of research and they vary significantly, depending on the vendor.
