Birthday Attacks


In data science, a birthday attack is a type of cryptographic attack that exploits the mathematics behind the birthday problem in probability theory. The birthday problem states that in a group of randomly chosen people, there is a high probability that two people will share the same birthday. Similarly, in cryptography, a birthday attack takes advantage of the fact that in a large enough set of randomly generated cryptographic keys, there is a high probability that two keys will be the same. This vulnerability can be exploited by an attacker to compromise the security of a system. To prevent birthday attacks, cryptographic algorithms use longer key lengths and more complex hashing functions to reduce the likelihood of two keys being the same.
