DES加密算法及其在Java中的实现
(maximal if j == k). In myimplementation this is always the case; (7). Selection of a small value for jwill require more cycles through the encipherment algorithm per unit ofplaintext and thus cause greater processing overheads; (8). Onlymultiples of j bits can be enciphered; (9). ...
