Multi Authority File Hierarchy Ciphertext Policy Attribute Based Encryption Schemes with Hidden Access Policy for Enhancing Security in Cloud Storage

Abstract

Cloud computing is one of the most significant computing model, which provides easy access of resources. It is an alternative for costlier data framework and networking models. The services are provided to the data users based on their requirements. More industries are depending on the cloud, because of its fast computations and robust nature. However, there are several security concerns and threats in cloud storages. Moreover, large amounts of data are shared between people and organizations through the cloud. The data owner doesn t have control over the data in the cloud. To address the security and privacy issues in the cloud, this thesis aims at overcoming this trade-off, while considering security. newline
