| Popis: |
To solve the information leakage problem resulting from several assertions of previous range query solutions,there is a secure range query scheme with one assertion (SRQSAE scheme),and the scheme is claimed to be secure against ciphertext-only attack.The security analysis on SRQSAE scheme is presented,and it shows SRQSAE scheme can not hide the size of search keyword.A new scheme of secure range query on encrypted data is proposed through introducing random numbers in the generation of search index and trapdoor.The new scheme can provide the privacy guarantee on search range and search keyword,and it achieves high level needs of security without losing efficiency. |
