Challenge-Response Authentication

Challenge-Response Authentication: A method of authentication where one party presents a challenge (often a random number) and the other party must provide the correct response, which is based on a shared secret.

Analogy: Like a security guard asking a secret password, it verifies identity through a pre-agreed upon exchange.

Why It Matters: It is a common method for verifying identity in systems where storing passwords in plain text is not secure.
