CISSP: ECB. Electronic Code Book (ECB) mode does not use any chaining. This means that the same plaintext will create the same ciphertext every time it is encrypted with the same key. The other DES modes use chaining, which means some of the previously encrypted data is used in the encryption process. These modes do not provide patterns as the ECB mode does.
