Question

If a system uses encryption to protect data, why is authentication still required to ensure the security of the overall network?

Accepted Answer

Encryption is like putting your letter inside a locked safe. It keeps the information private so nobody can read it while it travels. But encryption does not tell you who put the letter in the safe. Authentication is the process of checking someone&#x27;s identity to make sure they are who they claim to be. Think of it like showing your ID card to a guard before you enter a building. If you have a locked safe but you do not know who has the key, a bad person could trick you into giving them the safe or pretending they are the owner. Authentication ensures that only the right people can unlock the data or send commands to the system. Without it, anyone who gets their hands on the encrypted data might be able to pretend they belong there. Encryption keeps secrets safe from prying eyes, but authentication makes sure the right people are the ones using the system.
