A Numeric Cipher Method ( additive ); Mixed with transposed key groups....

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
