Abstract: The amount of data is growing and a demand for big data storage significantly increases. Through the cloud center, data providers can conveniently share data stored in the center with others. However, one practically important problem with big data storage is privacy. During the sharing process, data is encrypted to be confidential and anonymous. Such operations can protect privacy from being leaked out. To satisfy the practical conditions, data transmission with multiple receivers is also considered. Furthermore, this work proposes the notion of pre- authentication for the first time, i.e., only users with certain attributes that have already. The pre-authentication mechanism combines the advantages of proxy group key conditional re-encryption multi-sharing mechanism with the attribute-based authentication technique, thus achieving attribute authentication before re-encryption, and ensuring the security of the attributes and data. Moreover, this work finally proves that the system is secure and the proposed pre-authentication mechanism could significantly enhance the system security level.
