摘要：Cloud storage provides a convenient, massive, and scalable storage at low cost, but data privacy is a
major concern that prevents users from storing files on the cloud trustingly. One way of enhancing privacy from data
owner point of view is to encrypt the files before outsourcing them onto the cloud and decrypt the files after
downloading them. However, data encryption is a heavy overhead for the mobile devices, and data retrieval process
incurs a complicated communication between the data user and cloud. Normally with limited bandwidth capacity and
limited battery life, these issues introduce heavy overhead to computing and communication as well as a higher power
consumption for mobile device users, which makes the encrypted search over mobile cloud very challenging. In
proposed system, we propose TEES (Traffic and Energy saving Encrypted Search), a bandwidth and energy efficient
encrypted search architecture over mobile cloud. The proposed architecture offloads the computation from mobile
devices to the cloud, and we further optimize the communication between the mobile clients and the cloud. It is
demonstrated that the data privacy does not degrade when the performance enhancement methods are applied. Our
experiments show that TEES reduces the computation time and save the energy consumption on file retrieval,
meanwhile the network traffics during the file retrievals are also significantly reduced.
