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 … See more As an example, consider the scenario in which a teacher with a class of 30 students (n = 30) asks for everybody's birthday (for simplicity, ignore leap years) to determine whether any two students have the same … See more Digital signatures can be susceptible to a birthday attack. A message $${\displaystyle m}$$ is typically signed by first computing See more Given a function $${\displaystyle f}$$, the goal of the attack is to find two different inputs $${\displaystyle x_{1},x_{2}}$$ such that $${\displaystyle f(x_{1})=f(x_{2})}$$. Such a pair $${\displaystyle x_{1},x_{2}}$$ is called a collision.
