Can technological achievements involving state secrets apply for public patents without decryption?
You can't. You can't apply for any patent for top secret national defense inventions, because the premise of applying for patents is to make them public. Once made public, state secrets will be leaked, so you can't apply for a public patent. Patent disclosure refers to an invention method in which the invention requested for protection is disclosed in written form through scientific publications, or in oral form through speeches, or the invented articles or articles are displayed at exhibitions.
