Cloud computing is an emerging computing paradigm, enabling users to store their data remotely in a server and to provide services on-demand. In cloud computing, cloud users and cloud service providers are almost clear from different trust domains. The critical issues for remote data storage are data security and privacy. A secure user enforced the data access control and that mechanism must be provided before the cloud users have liberty to outsource delicate data to cloud for storage. With the emergence of sharing personal data on cloud servers, it is essential to acquire an efficient encryption system with a fine-grained access control to encrypt outsourced data. Attribute-Based Encryption is a public key based encryption that enables access control over encrypted data using access policies and ascribed attributes. In this paper, we are going to analyze various schemes for encryption and possible solutions for their limitations that consist of Attribute Based Encryption (ABE), CP-ABE, HABE, MA-ABE, KP-ABE.
