Question:
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?

Replies:
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.
