    Abstract:

    With the development of cloud computing, the issue of secure search with ciphertext retrieval as the key technology has become a hot topic at worldwide. In order to improve the security of the ciphertext retrieval scheme, a verifiable ciphertext retrieval scheme is designed based on inverted index. First, insert the confusion keywords when building trapdoorstoagainst a malicious cloud server's keywords attack. At the same time, the data cache area is introduced, which utilize the Pailliar encryption technology to blindly calculate the search results containing the obfuscated keywords, and the ciphertext data other than the target keyword is filtered out to reduce the communication overhead. Secondly, take advantage of bilinear maps generate tags to verify search results, and verify the scheme in terms of correctness, security and reliability. Repeated experiments on real data sets, theoretical analysis and experimental results show that the proposed scheme can improve the security of ciphertext retrieval compared with the existing ciphertext retrieval schemes while ensuring retrieval efficiency.
