Birthday attack in network security

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 … 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 $${\displaystyle f(m)}$$, where $${\displaystyle f}$$ is a cryptographic hash function, and then using some secret key to sign 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. The method used to find a collision is … See more • Collision attack • Meet-in-the-middle attack See more • "What is a digital signature and what is authentication?" from RSA Security's crypto FAQ. • "Birthday Attack" X5 Networks Crypto FAQs See more
