Reading What is Public Key Infrastructure (PKI)

Name the three main components which make up PKI.

1. Public Key
2. Private Key
3. Certifying Authority

How would you explain, to a non-technical friend, the role PKI plays in protecting traffic between your browser and a web server.

Public Key- the name your parents gave you private key- the name that is like a nickname, but only you respond to it certifying authority- the certificates and forms that require this information

There is a message that was sent to you. Since it's for you, it has your name on it (public key). But your sister wrote it and the message has a hidden meaning behind the superficial words she used in the message. since your name doesn't truly confirm that it's you, how to know it's really you that is reading this. Your nickname-the real you- (private key) (the you that grew up with your sister and has a bunch of inside jokes only you and she know. But since computers are not as smart as us yet, all this has to be done by means of a some kind of certificate, which isn't as secure as what goes on in your head that is never spoken of that is even hidden from the part of you that is conscious.

A certificate authority can sign a certificate for any person or computer and people can always use fraudulent certificates Videos Prof Messer Security+ PKI Components
