Parallel incremental attribute-based encryption for mobile cloud data storage and sharing

Aiming at the problem of one to many communication scenarios in mobile cloud computing, a parallel incremental attribute-based encryption is proposed. An incremental attribute-based encryption scheme is brought, which is used to protect sensing data and share to many receivers securely and improve the access control ability further. To achieve a balance between efficiency and energy consumption, the scheme uses the idea of parallel computing, fully exploits the performance of existing mobile clients, and achieves a balance between efficiency and energy consumption. In the experiments, parallel computing can improve the efficiency of schemes, make full use of hardware resources, and improve the efficiency of the serial scheme by about 55% in the best case.
