WebCryptographic attacks ... This attack relies on a mathematical theory called the birthday problem, which says that statistically, in a set of randomly selected people, some pairs of people will have the same birthday. The probability increases as the number of people grows. In cryptography, the data integrity is established using a WebThe birthday attack is named after the birthday paradox. 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.
