WebThe application of the birthday paradox in cryptography is known as the birthday attack. This attack is made to break the collision-resistant property that is desirable in cryptographic hash functions. A collision-resistant attack intends to find two messages that will have the same message digest or hash value.

WebWe saw a general attack on block cyphers which we called exhaustive search. And that attack forced the key size for a block cypher to be 128 bits or more. Similarly on collision resistance there is a general attack called the birthday attack which forces the output of collision resistant hash functions to be more than a certain bound.
