摘要：Cloud computing is an emerging computing paradigm enabling users to remotely store their data in a server and provide on-demand services . With the emergence of sharing confidential corporate data on cloud server, data security and privacy became the critical issues for remote data storage. Secure user enforced data access control mechanism must be provided before cloud user has the liberty to outsource sensitive data to the cloud for storage. In present many cryptographic algorithms are used for encryption of the data. 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), Key policy Attribute based encryption(KP-ABE), Cipher text Attribute based encryption(CP-ABE), non-monotonic access structure, Hierarchical Attribute based encryption(HABE), Multiple authority Attribute based encryption(MA-ABE).
