WebMar 19, 2024 · Using this formula, we can calculate the number of possible pairs in a group = people * (people - 1) / 2. Raise the probability of 2 people not sharing a birthday to the power pairs i.e P (B). Now, we have the probability of no one having a common birthday i.e P (B). So, find chance of atleast two people celebaring on the same date i.e. P (B'). WebThe math behind the birthday problem is applied in a cryptographic attack called the birthday attack.

What is Birthday attack?? By Ganesh Gupta Abstract

Given a year with d days, the generalized birthday problem asks for the minimal number n(d) such that, in a set of n randomly chosen people, the probability of a birthday coincidence is at least 50%. In other words, n(d) is the minimal integer n such that The classical birthday problem thus corresponds to determining n(365). The fi… WebBirthday attack can even be used to find collisions for hash functions if the output of the hash function is not sufficiently large. ...
