An Encrypted Index Mechanism in Ciphertext Retrieval System
The ciphertext-based full-text retrieval technology is proposed to satisfy the pressing demands for high security in massive information sharing applications. Based on the analysis of general technology of full-text indexing, we propose an improved index structure that supports ciphertext indexing and retrieval. Then we present approaches to construct, maintain and retrieve ciphertext indexes. Meanwhile, we implement a ciphertext- based full-text retrieval system, which allows fulltext search on the encrypted documents in multiple formats without decryption. Finally, we carry out the experiments and evaluate the performance of ciphertext index construction and retrieval.
