In yum, it really does not matter if enemy takes over the internet and fakes to be some website offering software. All software is cryptographically checked before installation. To install some software, we must tell yum who we trust.
rpm --import /usr/share/doc/yum-*/Fedora-GPG-KEY
rpm --import /usr/share/doc/yum-*/RPM-GPG-KEY
Because fedora rpm contains the keys, this appendix does not seem too necessary.
For help installing these keys, see Add trusted authors to your keyring above.
