| Abstract: | In order to ensure the confidentiality, integrity and operability of the outsourced database, the traditional Merkle tree structure is modified, combined with broadcast encryption, bilinear accumulator and other methods, a new outsourcing database multi-user and multiple keywords ciphertext search scheme has been proposed. The scheme can verify the completeness of multi-keyword search results. Compared with the existing solution, this solution is more flexible, and the required verification information storage space is smaller, and the data required for verification is less. |
