Abstract
Cloud storage provides a massive, and scalable storage. Provider will encrypt the data and upload in cloud. User search for required data and decrypt it. 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. TEES, a bandwidth and energy efficient encrypted search architecture over mobile cloud is used for document retrieval. It is based on single keyword search. In this paper, an enhanced TEES scheme using multi keyword search is proposed. It reduces the consumption of time, bandwidth and mobile energy rate.
