Digital Certificates - How
- example of hierarchy:
- Eric approaches me and says, "Hey. I'm Eric."
- So I check his ID, and find out that the CA is Tim.
- Tim's Digital Signature is on the ID, but who is this
Tim person, and how do I know this is his signature?
- But attached is another ID, issued by Professor Paturi.
- Ok, I know Paturi, and I have his public key so I can
verify his digital signature.
- I also know that Paturi only gives IDs to CAs that do
blood sampling before giving out IDs.
- The signature passes.
- So I trust Paturi, so I believe that this is Tim's
signature, so therefore I believe that this guy is indeed
Eric.
