An updatable encryption scheme allows to periodically rotate the encryption key and move already existing ciphertexts from the old to the new key. These ciphertext updates are done with the help of a so-called update token and can be performed by an untrusted party, as the update never decrypts the data. Updatable encryption is particularly useful in settings where encrypted data is outsourced, e.g., stored on a cloud server. The data owner can produce an update token, and the cloud server can update the ciphertexts.
