The sharing of personal data with multiple users from different domains has been benefited considerably the rapid advances cloud computing, and it is highly desirable to ensure file should not be exposed unauthorized or providers. Unfortunately, issues such as achieving flexible access control file, preserving privacy receivers, forming receiver groups dynamically, high efficiency in encryption/decryption still remain challenging. To deal these challenges, we provide a novel anonymous...
