Abstract
In today’s networked world, a huge amount of data is being generated by various physical devices for communication. It is due to a sudden surge in the use of IoT devices in various sectors like health monitoring, automobile industry, home appliances etc. These data objects are stored in the cloud which consists of sensitive data objects along with other information. Cloud storage is a physical cyber system that attracts users from all sectors to store their data in it. Data storing in the cloud is useful to the individual/organizations to save their maintenance cost. Sharing those stored data through the cloud makes the organization improve their business. Though it increases the business it also increases security challenges. A lot of researches has done to provide secure data sharing through cloud storage. Still, more mechanisms are required to fulfil the requirements of secure data sharing. . The possible attacks at cloud storage are Known-ciphertext, Known-Plaintext and Guessing-keyword. Techniques for secure data sharing through cloud Searchable Symmetric encryption (SSE).Public Key Encryption with Keyword Search (PEKS), Attribute-Based Encryption (ABE). Earlier research focuses on user attributes for secure data sharing. But, organizations point of view they will have levels of priority to get access to the data. The proposed framework encrypt the data based on user priority levels before outsourcing the data and allocates credentials based on priority level hierarchy. The data-sharing architecture should able to support user attribute revocation as well as the priorities revocation. It should able to provide verifiability regarding the accuracy of the cloud service provider’s search on behalf of the data user. In the proposed architecture the index format includes encrypted keyword which is constructed with access policies and time. The user priorities are considered along with attributes.

Cloud storage is a physical cyber system that attracts users from all sectors to store their data in it.
