Abstract
Described herein is an efficient, dynamic Symmetric Searchable Encryption (SSE) scheme. A client computing device includes a plurality of files and a dictionary of keywords. An index is generated that indicates, for each keyword and each file, whether a file includes a respective keyword. The index is encrypted and transmitted (with encryptions of the files) to a remote repository. The index is dynamically updateable at the remote repository, and can be utilized to search for files that include keywords in the dictionary without providing the remote repository with information that identifies content of the file or the keyword.
