  • 摘要:Cloud computing is emerging as a prevalent data interactive paradigm to realize multiple users data remotely stored in an online cloud server. During the data accessing, different users may be in a collaborative relationship, and subsequently information sharing gets to be noteworthy to accomplish gainful advantages in the business application. The existing solutions mainly focus on the authentication to realize that a user's privat ive data cannot be un - authorized accessed, but neglect a subtle privacy issue during a user challenging the cloud server to request other users for data sharing. The challenged access request itself may reveal the user's privacy no matter whether or not i t can obtain the data access permissions. This shared authority based directory services authentication protocol to address above privacy issue for cloud storage. Shared access authority is achieved by Lightweight Directory based authentication Protocol fo r create many directory services. Attribute based access control is adopted to realize that the user can only access its own data fields. AE - Attribute encryption is applied by the cloud server to store and retrieve data, and to provide data sharing among t he multiple users. Meanwhile, universal compos ability model is established to prove that the SADA theoretically has the design correctness. It indicates that the proposed protocol realizing privacy - preserving data access authority sharing is attractive fo r multi - user collaborative cloud applications
