The name is based on the fact that in a room with 23 people or more, the odds are greater than 50% that two will share the same birthday. Many find this counterintuitive, and the birthday paradox illustrates why many people's instinct in probability (and risk) is wrong.

WebMar 31, 2024 · The intuition is that \(2^n\) is the cost of running a brute force attack to retrieve an n-bit key, or the inverse success probability of a trivial attack that guesses the key at random.
