Abstract: A method of searching encrypted data includes generating with a client computing device a search index identifier corresponding to a search term in an encrypted search table and transmitting the search index identifier, a first single use key and a second single use key to a server. The method includes generating a set of decrypted data with the server for a set of data in an encrypted search table corresponding to the search index identifier using the first single use key to decrypt a first portion of the data and the second single use key to decrypt a second portion of the data. The method further includes identifying one or more encrypted files stored on the server that include the encrypted search term based on the decrypted data from the search table, and transmitting the encrypted files or encrypted file identifiers to the client computing device.
