In recent years, the secure search of encrypted cloud data has become a hot research topic and a challenging task. Several secure search schemes have been proposed to address this challenge. However, existing public-key searchable encryption schemes still face many problems. Among these schemes, most of them are based on single-key searchable encryption schemes, and although some schemes are designed for multi-key search, they still disclose the secret information of the encrypted index. Based on this, this paper proposes a multi-key public-key searchable encryption scheme without a secure channel, which uses a random element padding method to construct an encrypted index to ensure the security of the index information, and then improves the efficiency of the search by aggregating the query keyword information to generate query trapdoors. The simulation results of the algorithm show that the algorithm improves the query efficiency and query accuracy under the condition that the index and trapdoor are secure.
KEYWORDSSearchable encryption, multi-keyword, random element padding
