Once the courier had verified the identity and the PIN number had been established, you would have everything you need to securely send information. You would ask your recipient to come up with the second half of the number and send it to you in their return letter. The key establishment phase would be a little bit like if your letter contained half of a PIN number that you intended to use in future communications. When the courier delivers the letter, they would compare the person’s ID to their face and verify whether or not the recipient was the correct person. To return to our letter analogy, the authentication part of TLS would be kind of like sending a letter via a courier that requires identification. It starts with what is known as a TLS handshake, which is where authentication takes place and the keys are established. TLS fulfills these requirements using a number of different processes. Instead, you need a system that allows you to verify that your recipient is legitimate, a way that you can check whether messages have been altered, and a way to protect them from prying eyes.
You can’t just send a letter and hope for the best, especially if you suspect that your communications will be targeted by attackers. If the information is sensitive, you will be very worried about the three major problems mentioned above. Let’s simplify things and pretend that you are trying to transfer information back and forth with a friend who lives across the country. Together, they allow the protocol to authenticate the other party in a connection, check the integrity of data and provide encrypted protection. TLS uses a range of cryptographic techniques to address each of these three problems. These issues are crucial, especially when we are sending sensitive or valuable information. How can we prevent other people from seeing and accessing the data?.
