ABSTRACT: A search strategy over encrypted cloud data
based on keywords has been improved and has presented a method using different
strategies on the client and the server to improve the search efficiency in
this paper. The client uses the Chinese and English to achieve the synonym
construction of the keywords, the establishment of the fuzzy-syllable words and
synonyms set of keywords and the implementation of fuzzy search strategy over
the encryption of cloud data based on keywords. The server side through the analysis
of the user’s query request provides keywords for users to choose and topic
words and secondary words are picked out. System will match topic words with
historical inquiry in time order, and then the new query result of the request
is directly gained. The analysis of the simulation experiment shows that the
fuzzy search strategy can make better use of historical results on the basis of
privacy protection for the realization of efficient data search, saving the
search time and improving the efficiency of search.
