A Modified Simple Substitution Cipher With Unbounded Unicity Distance
Abstract
The classic simple substitution cipher is modified by randomly inserting key-defined noise characters into the ciphertext in encryption which are ignored in decryption. Interestingly, this yields a finite-key cipher system with unbounded unicity.
