Birthday attack in network security
WebJul 23, 2024 · 9. Birthday Attacks • The Birthday Attack exploits the birthday paradox – the chance that in a group of people two will share the same birthday – only 23 people are needed for a Pr>0.5 of this. Can generalize the problem to one wanting a matching pair from any two sets, and show need 2m/2 in each to get a matching m-bit hash. 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

Given a fixed message x with n-bit hash code h = H (x), a brute-force method of finding a collision is to pick a random bit string y and check if H (y) = H (x). The attacker can do this repeatedly off line.
