What are collision attacks in hashing?

Can you explain what collision attacks in hashing are?

Sure! Collision attacks occur when two different inputs produce the same hash output, compromising data integrity.

Why are collision attacks a concern in cryptography?

They can undermine the security of cryptographic systems, allowing attackers to forge signatures or manipulate data.

Can you give an example of a famous collision attack?

One well-known example is the MD5 collision attack, where researchers demonstrated that two different files could produce the same MD5 hash.

How can we prevent collision attacks?

Using stronger hashing algorithms like SHA-256 and implementing proper security measures can help mitigate collision attacks.
