摘要：In cloud computing, users can share data among group members with the characters of less maintenanceand little management cost. Sharing data must have security guarantees, if they are out sourced. Sharing data whileproviding privacy preserving is still a challenging problem, when change of the membership. It might cause to thecollusion attack for an unsecured cloud. For existing technique, security of key distribution is based on the securecommunication channel, however, to have such channel is a strong assumption and is difficult for practice. We proposea secure data sharing scheme for dynamic users. Key distribution done without any secure communication channels andthe user can get the individual key from group manager.Data deduplication is one of the techniques which used to solve the repetition of data. The deduplication techniques aregenerally used in the cloud server for reducing the space of the server. To prevent the unauthorized use of dataaccessing and create duplicate data on cloud the encryption technique to encrypt the data before stored on cloud server.CloudMe is proposed for cloud storage. All files of data owners are encrypted using AES algorithm and stored in realcloud.
