Abstract
In an encryption method, an input block of data is reversibly processed to produce a string that is at least partially randomized. The randomized string is then encrypted by a block cipher. In decryption, the input block of encrypted data is first decrypted with respect to the block cipher. Then the randomization is reversed.
