Birthday attack in information security
Did you know?
WebJul 27, 2014 · In an application where an attacker can succeed simply by finding any hash collision, the security level cannot exceed 128 bit since a simple birthday attack will (probabilistically) succeed after 2^128 random attempts. If you shorten the hash to a 128 bit hash, then you reduce its security level in this context to 64 bits. A birthday attack is a type of cryptographic attack that exploits the mathematics behind the birthday problem in probability theory. This attack can be used to abuse communication between two or more parties. The attack depends on the higher likelihood of collisions found between random attack attempts and a fixed degree of permutations (pigeonholes). With a birthday attack, it is possible to find a collision of a hash function in , with being the classical preimage resistance secur…
