    • The present invention provides a method, apparatus and system for fast searchable encryption. The data owner encrypts files and stores the ciphertext to the server. The data owner generates an encrypted index according to each keyword of the files, and stores the encrypted index to the server. The index is composed of keyword item sets each being identified by a keyword item set locator and containing at least one or more file locators of the files associated with the corresponding keyword. Each file locator contains ciphertext of information for retrieval of an encrypted file and only with the correct file locator decryption key can the ciphertext be decrypted. Data owner issues a keyword item set locator as well as file locator decryption key to a searcher to enable the searcher to search on the encrypted index and retrieve files related to a certain keyword.
    • 本发明提供了一种用于快速搜索加密的方法,装置和系统。 数据所有者加密文件并将密文存储到服务器。 数据所有者根据文件的每个关键字生成加密的索引,并将加密的索引存储到服务器。 索引由关键字项集合组成,每个关键字项集由关键字项目集定位符标识并且包含与相应关键字相关联的文件的至少一个或多个文件定位符。 每个文件定位器都包含用于检索加密文件的信息的密文,并且只能使用正确的文件定位器解密密钥来解密密文。 数据所有者向搜索者发出关键字项集合定位器以及文件定位器解密密钥,以使搜索者能够搜索加密的索引并检索与特定关键字相关的文件。
