Encrypted XML Data Query Processing with Range Query
Without decrypting the encrypted blocks, it is difficult to query encrypted XML data. Inspired by Query-Aware decryption scheme, the paper extends the scheme to support range query with value index. Value index is based on order preserving encryption. The testing results indicate that the proposed scheme can complete a correct query processing, and support range query.
