EnDAS: Efficient Encrypted Data Search as A Mobile Cloud Service.

Abstract

Document storage in the cloud infrastructure is rapidly gaining popularity throughout the world. However, it poses riskto consumers unless the data is encrypted for security. Encrypted data should be effectively searchable and retrievable without anyprivacy leaks, particularly for the mobile client. Although recent research has solved many security issues, the architecture cannot beapplied on mobile devices directly under the mobile cloud environment. This is due to the challenges imposed by wireless networks,such as latency sensitivity, poor connectivity, and low transmission rates. This leads to a long search time and extra network trafficcosts when using traditional search schemes. This study addresses these issues by proposing an efficient Encrypted Data Search(EnDAS) scheme as a mobile cloud service. This innovative scheme uses a lightweight trapdoor (encrypted keyword) compressionmethod, which optimizes the data communication process by reducing the trapdoor’s size for traffic efficiency. In this study, we alsopropose two optimization methods for document search, called the Trapdoor Mapping Table (TMT) module and Ranked Serial BinarySearch (RSBS) algorithm, to speed the search time. Results show that EnDAS reduces search time by as well as networktraffic.
