A method, for some brief messages, might be this: Given a numeric key-pad, insert a "Group Key Transposition Indicator" ( e.g.: 53124 ) as the 6th Key Group. Encrypt by addition. After the addition, add the Key Encrypting Key ( e.g.: 00321) ; then transpose the order of the next 5 new keygroups. encrypt the next part of message with the next key group. It can be more flexible, if you change the Key Encrypting Key, every 6 key-groups: First was 00321; next might be 00624; or 00531. So.: 84457,20026,01731,46846,11207,53124,11528,01052 84778,20347,47167, ( from pad, new ) 97163,76669,22502,17720 19446,24135 . ( 24135 would be the Group Key Transposition Indicator. ) After seeing "24135", I would add 00321 to each of the previous key groups, then transpose them in the order indicated. This is just for friends, colleagues, going "old school" . The math is a bit interesting; though not terribly advanced. Have a good weekend. Joe // Saturday 12 April 2014 / 11.12 EDST NJ USA // |
