As Cloud Calculating becomes prevalent, extra and extra sensitive data are being centralized into the cloud, such as emails, confidential condition records, confidential videos and photos, firm finance data, power documents, etc. By storing their data into the cloud, the data proprietors can be relieved from the burden of data storage and maintenance so as to relish the on-demand elevated quality data storage service. Though, the fact that data proprietors and cloud server are not in the alike trusted area could locale the our sourced data at chance, as the cloud server could no longer be fully trusted in such a cloud nature due to a number of reasons: the cloud server could leak data data to unauthorized entities or be hacked. It follows that sensitive data normally ought to be encrypted prior to outsourcing for data privacy and combating unsolicited accesses. In cloud computing cloud users and cloud ability providers are nearly precise to be from disparate belief domains. Data protection and privacy are the critical subjects for remote data storage. A safeguard user enforced data admission manipulation mechanism have to be endowed beforehand cloud users have the freedom to outsource sensitive data to the cloud for storage. With the rise of allocating confidential company data on cloud servers, it is imperative to accept an effectual encryption arrangement alongside a fine-grained admission manipulation to encrypt outsourced data. Attribute-based encryption is a area key established encryption that enables admission manipulation above encrypted data employing admission strategies and ascribed attributes. In this work, we are going to scutiny homomorphic schemes for encryption and probable resolutions for their limitations.
