A Novel Integrity-Verification based Secured ABE model for cloud computing

Abstract

Cloud environment has emerged as a flexible,
computational cost and scalable to solve the problems of
increasing on-demand requirements on shared computing
resources. Data security and access control are the major
issues in the cloud environment, as users often store their
sensitive data by the third party authorities. Attribute based
encryption and decryption models have been widely used in
the cloud server for not only hiding the data but also provide
user access control. Many cloud based privacy protection
solutions have been implemented in the literature, however
most of them only focus on limited data size and storage
format. With the increase in attribute and user policies, tree
size growth also exponentially increases which is very
difficult to the user to access the information.
