To improve the precision of traditional ciphertext retrieval techniques,a scheme of ciphertext retrieval in cloud based on ontology semantic expansion is proposed.The scheme brings the ontology into ciphertext retrieval by building a hybrid cloud ciphertext retrieval model.The ontology concept structure is used to expand the query keyword semantically.The extended results are filtered by the semantic similarity so as to understand the intention of the user better.Experimental results show that the method can improve the accuracy of the search results while ensuring the retrieval speed.
