Cloud computing is an emerging technology. It is a basic paradigm which satisfies all the needs of a customer and it may even serve as a fifth utility in near future. In general it refers to both the applications delivered as services over the Internet and the hardware and systems software in the data centers that provide those services. The data center hardware and software is known as a cloud. A huge amount of data is being processed and shared. So, while we are sharing a large amount of data through online there is a chance for the data to get modified by someone else. In order to protect this data from getting modified we provide several security mechanism like access control. One of the mechanism would be by encrypting and sending the data. Encryption plays a major role in protecting the data. Many encryption schemes were proposed but it cannot survive long due to efficiency constraint. So firstly attribute based encryption was proposed which was later modified to key policy based encryption scheme which was again modified by cipher text encryption scheme is and was later again switched to file hierarchy cipher text based encryption. So my project mainly concentrates on File Hierarchy Attribute Based Encryption scheme in which we make use of Hierarchical structures and attributes matching which is mainly important for providing access control to the data.
