Security Coding Method

This invention relates to a method for security and coding bit strings using a two-stage random key selection. The pseudo randomizing encoding and recovery steps are set out in the following APL implementable listings:
ENCODE FUNCTION (ECD)

DECODE FUNCTION (DCD).

A 25-character string "SAN JOSE CALIFORNIA 95193" is the variable to be encoded (see next page). A trace of the encoding steps is shown together with a trace of the recovery steps. see original
