Uncipherable code
Author: heidi g bergmann
I have been doing a study on cryptology. Is there such a thing as an
uncipherable code, even using word/letter frequencies? How would such a
code be composed, and what exactly keeps it from being able to be decoded?

If you use a code where you change the entire code with each succeeding
letter, then using word/letter frequencies does not help in the deciphering.
This is the kind of code used in modern encryption systems - the conversion
changes based on a "key" that is passed between the two people who want to
keep their communications secret.
