WebKaspersky IT Encyclopedia. Glossary. b. Birthday attack. A method of cracking cryptographic algorithms through matches in hash functions. It is based on the birthday paradox, according to which the probability of two people sharing a birthday is far higher than it seems — for a group of 23 people, for example, the probability is 50%. WebIn a typical case (e.g., the attack on MD5) only a relatively small number of specific inputs are known to produce collisions. Collision resistance obviously means that a collision attack is difficult (for some definition of "difficult" varying from "no attack better than brute force is known" to "the known attacks aren't really feasible").
