  • Method and system for search pattern oblivious dynamic symmetric searchable encryption
    Patent number: 11144663
    Abstract: An oblivious encrypted search and update method includes transmitting encrypted search queries and encrypted file update requests from a trusted client to at least two different untrusted servers, receiving encrypted search entries and encrypted file entries from the untrusted servers, and decrypting the encrypted search entries and encrypted file entries with the trusted client. The trusted client re-encrypts the decrypted entries and transmits re-encrypted entries that were received from a first untrusted server to a second untrusted server and vice versa to provide obliviousness for encrypted keyword searches and encrypted file updates from the trusted client.
