Abstract

Abstract:

Already there has been many keyword searchable encryption researches done, but they mostly bear a weakness of offline keyword guessing attack, besides they are based on the heavier pairing computation. What’s more, most public encryption keyword search schemes can’t support fuzzy keyword search, this obvious drawback reduces the usability of the search system. The scheme we propose use the server’s public key to encrypt the keywords and data, and if outside attackers have no server’s private key, he will not obtain any information of the keyword ciphertexts, so we can use public channel to transport PEKS. The scheme not only supports accurate keyword search encryption but also supports the search when the keywords input have any spelling mistakes or format inconsistent situations. So it has greatly improved the availability of the system. The scheme use El Gamal encryption instead of the bilinear-pairing encryption, which greatly reduce the computational overhead.

Key words: cloud computing, no bilinear pairing, fuzzy, El Gamal
