摘要：Cloud Computing provides many services among them storing data. Storing user’s data at the cloudfrees the burden of user’s devices and it leads to better access of data. Due to distrust in cloud service providers dataowners normally store their data in an encrypted form. But in various conditions, data need to be accessed by otherentities to achieve an expected service, e.g., an eHealth service. By this control of personal data access at the cloud is avital issue. Various applications scenarios request for flexible, fine-grained access control and better dataconfidentiality. Although the existing access control mechanism does not find a suitable solution. Furthermore, trustplays a main role in data sharing. Trust helps to control uncertainty and avoid the potential risks. But literature stillneeds a solution to access control of data based on trust and reputation. The proposed system provides an efficientaccess control mechanism which is applied by the data owner and reputation center in a flexible manner byimplementing Attribute-Based Encryption and Proxy Re-Encryption.
