Abstract: | Searchable encryption is a cryptographic primitive that supports keyword search on ciphertexts. It can save users a lot of network and computing overhead. Complex semantic searchable encryptions mainly include wildcard searchable encryption, fuzzy keyword searchable encryption, and multi-keyword searchable encryption, which can support users to search ciphertexts in various forms, not limited to complete single keyword search, and are more suitable for the actual searching requirements of users. This paper mainly studies the research status, typical structure, and the relationship among the three types of complex semantic searchable encryption, and gives a new keyword feature extraction method, so that the wildcard searchable encryption can be transformed into the general multi-keyword searchable encryption. Finally, some existing problems in complex semantic searchable encryptions and some future research ideas are discussed. |
