It's a simple substitution cipher. A mnemonic one. It takes 10 minutes to break it.
I don't think it was created for secrecy. It was used in manuscripts that showcase his engineering ideas. I think the cipher is a way to demonstrate his abilities when combined with the engineering diagrams.
In this blog I demonstrate the mnemonic techniques used in Fontana's cipher, some of which I believe I was the first to record.
Fontana explicitly wrote about mnemonics, so his mnemonic cipher fits right in. As I pointed out in the blog summary, I think his cipher was a way to demonstrate the use of mnemonics (and to showcase his skills):
