What are collision attacks in cryptography?

What are collision attacks in cryptography?

Collision attacks are methods used to find two different inputs that produce the same hash output, compromising data integrity.

How do collision attacks work?

They exploit weaknesses in hash functions by generating multiple inputs and checking if they yield the same hash value.

Can you give an example of a collision attack?

Sure! A famous example is the MD5 hash function, which has known vulnerabilities that allow for collision generation.

What are the implications of collision attacks?

They can lead to data forgery, unauthorized access, and undermine trust in digital signatures and certificates.
