pretty good privacy materials needed(this is for coursework)

shivajikobardan

I need materials to study pretty good privacy.I need how authentication and confidentiality is done explanations with a block diagram.

I picked up a keyword “pretty good privacy” “authentication” “confidentiality”

I searched the zlibrary website for text search. Downloaded lots of books, but none of them had this information.

I searched books.google.com for the same keyword but again did not found relevant books.

Then I searched google. While there are plenty of materials, I am not really satisfied with them.

These are few of the best-:

https://slideplayer.com/slide/10850690/

https://www.geeksforgeeks.org/pgp-authentication-and-confidentiality/

If you have some good legacy books or sth where you have both explanations and figures of these  cases, could you share it? Would be really useful for me.

Or if this topic is in your mind already, you could share it here in this forum as well directly.
