SYSTEMS AND METHODS FOR PERFORMING DOUBLE ENCRYPTION TO INHIBIT MEET-IN-THE-MIDDLE ATTACKS

摘要

Methods and systems are provided for the encryption of data. In one embodiment, the invention provides a method for performing double encryption and applying whitening while providing a key length of at least 2n where the key of the original cipher is n bits. This is provided in a way that requires less work than three applications of the cipher and avoids a meet-in-the-middle attack to which double encryption by itself would be subject.
