| Descripción: | As Cloud Computing becomes prevalent, moreand more sensitive information are centralized into thecloud. In thispaper, for the first time we formalize and solve the problemof efficient conjunctive fuzzy keyword search overencrypted cloud data while maintaining keyword privacy.Conjunctive fuzzy keyword search greatly enhances systemusability by returning the matching files when users'searching inputs exactly match the predefined keywords orthe closest possible matching files based on keywordsimilarity semantics, when exact match fails. In our solution,we exploit edit distance to quantify keywords similarity.Through rigorous security analysis, we show that ourproposed solution is privacy-preserving. |
