CREATING DETERMINISTIC CIPHERTEXT USING WIDE-BLOCK ENCRYPTION

Abstract:

A computer-implemented method according to one embodiment includes compressing an uncompressed instance of data to create a compressed instance of data; encrypting the compressed instance of data utilizing wide-block encryption in response to determining that a size of the compressed instance of data is less than a predetermined threshold; and adding a zero pad to the encrypted compressed instance of data to create a ciphertext string.
