But even if I use keyword-mixed alphabets for substitution, the concept of the system is still going to be substitution which is fairly easy to break. Substitutions simply put me off. One of my friends who is an amateur symbologist gave a message in his new language and asked me to break it. I found out the message within 2 days because it was all substitution. Even though the system you use may be complex, but if it results only in substitution then the system is not at all secure. The thing which struck me when I read your above post is that why not use the keyword-mixed alphabets in a complex way and then add the values of their corresponding alphabets and then prepare the ciphertext? Or else even process the keyword-mixed alphabets in such a way that cryptographers drop the idea of a keyword based system?
