Abstract
With the rapid development of mobile social networks and cloud servers, more and more people will outsource their personal profiles for sharing in cloud. Compared to traditional web-based online social networks, the mobile social networks can assist users to easily discover and make new social interaction with others. To keep the shared data confidential against untrusted cloud service providers and solve the problem of single point failure as well as performance bottleneck, we propose a secure distributed multi-authority attribute-based encryption scheme without central authority, so as to provide not only fine-grained access control, but also high security and performance. By employing this scheme, users can achieve fine-grained access control and privacy preserving.
