Abstract
Techniques are disclosed for securing data stored on a minimally trusted third-party data store. The techniques include directing all messages for storing data and retrieving stored data through a security server. The security server can be configured to receive encrypted data for storage at a remote data store, decrypt the encrypted data, generate index information for the decrypted data, encrypt the index information, encrypt the decrypted data to produce re-encrypted data, digitally sign the re-encrypted data, and cause transmission of the re-encrypted data and the encrypted index information to the remote data store. To access stored data, the security server can be configured to receive a query for stored data, encrypt the query, cause transmission of the encrypted query to the remote data store, receive a copy of the stored data, process the copy of the stored data, and cause transmission of the stored data to the requesting computer.
