Effective searchable symmetric encryption system using conjunctive keyword

Abstract

Removable Storage provides excellent portability with lightweight and small size to fit into one's hand. Many users have turned their attention to high-capacity products. However, Removable Storage devices are frequently lost and stolen due to their easy portability. Many problems, such as the leaking of private information to the public, have occurred. The advent of remote storage services, where data is stored throughout the network, has allowed an increasing number of users to access data. The main data of many users is stored together on remote storage, but this has the problem of disclosure by an unethical administrator or attacker. Data encryption on the server is necessary to solve this problem. A searchable encryption system is needed for efficient retrieval of encrypted data. However, existing searchable encryption systems have low efficiency for data insert/delete operations and multi-keyword search. This paper proposes an efficient searchable encryption system. © 2013 Springer Science+Business Media Dordrecht.
