Abstract: Implementations are directed, for example, to a method that includes receiving, at a data storage system from a client, a key search token that has not been used to encrypt data records or keywords associated with the data records. The key search token is independent of an encryption key used to encrypt the data records associated with the key search token. The method further includes determining an encrypted data record associated with the key search token, and transmitting the determined encrypted data record to the client. Implementations of the client are also provided.
