Efficient Search on Encrypted Data
Azman Samsudin · 2006
Encrypted data are being kept in remote server for purposes like backup and space savings. In order to retrieve these encrypted data, efficient search methods were proposed that enable the retrieval of the dataset without leaking too much information thus ensuring better security and less information leakage. An improved method is proposed in this paper for an efficient search on encrypted data which implements a keyword list in a hash table for each encrypted document. The keyword is encrypted in such a way that by providing the file server with required search information known as "a capability for a certain keyword", searches can be performed without leaking any information.
