This article finds that with the development of network technology and the change of a users' social habits, the existing multimedia social network, whether it is one-to-one authorization or one-to-many authorization, are having difficulty meeting the needs of users and cloud storage service. In order to solve this problem, this article proposes a new authorization scheme of multimedia community, based on attribute encryption. Use MA-CP-ABE solution to enhance system service efficiency. This program contributes to two aspects: (1) combining user trust with attribute-based authorizations, and (2) enhancing the flexibility and security of the solution. The scheme has been applied in the prototype system and achieved good results. Results prove that the program has good application value for cloud storage technology, IoT and many other fields.
