The first addresses traffic -analysis threats by hiding the size of the message and insuring that -if the same message is send repeatedly with the same -.I password -the ciphertext will be entirely different each time. -The second layer is the proposed Data Encryption Standard (DES) used -in Cipher Block Chaining (CBC) mode. Finally, a key-dependent character -transposition is applied to the ciphertext which impedes the -assembly of corresponding pairs of DES blocks under a known-plaintext attack. -.PP -The user is encouraged to use a lengthy password. A short sequence of -words chosen at random from a dictionary and committed to memory is -a good plan. -.SH FILES -/dev/tty for typed key -.SH AUTHOR -D.P.Mitchell -.SH BUGS -This encryption program is not provably secure, and the author gives no -guarantee that it cannot be broken. |
