Abstract

3 ABSTRACT: Many technologies are evolved on providing security to the cloud and its not possible to protect the whole cloud. Instead, we are focusing on providing security to data sharing terminology. In data sharing system, two important issues such as enforcement of access policies and support of policy updates is faced. One of the efficient cryptographic solution to solve these issue is XCP-ABE in which the user can define their own access policies and enforce these polices on the data to be distributed. Usually encryption and decryption is done by generating the private keys which is not suitable for data sharing scenarios. In proposed system, the encryption and decryption is done by providing additional secrets i.e..Generation of super keys. On observing the existing system it is found that, there are three major drawbacks such as Key escrow problem, invocation of users and lack of black box traceability which takes the advantages over the proposed one. This additional measure is an optional variant applicable to high sensitivity data subject to frequent access.
