WebA birthday attack is a type of cryptographic attack, which exploits the mathematics behind the birthday problem in probability theory. … In probability theory, the birthday paradox or birthday problem considers the probability that some paired people in a set of n randomly chosen of them, will have the same birthday. ... WebMuch like symmetric-key ciphers are vulnerable to brute force attacks, every cryptographic hash function is inherently vulnerable to collisions using a birthday attack. Due to the birthday problem, these attacks are much faster than a brute force would be. A hash of n bits can be broken in 2 n/2 time steps (evaluations of the hash function).
