Discuss EC-Council 212-81 Exam Topic 4 Question 8

What is a "Collision attack" in cryptography?

ACollision attacks try to break the hash into three parts to get the plaintext value

BCollision attacks try to get the public key

CCollision attacks try to break the hash into two parts, with the same bytes in each part to get the private key

DCollision attacks try to find two inputs producing the same

Suggested Answer: D

Collision attacks try to find two inputs producing the same

https://en.wikipedia.org/wiki/Collision_attack

A collision attack on a cryptographic hash tries to find two inputs producing the same hash value, i.e. a hash collision. This is in contrast to a preimage attack where a specific target hash value is specified.

I thought collision attacks were more complex than just matching outputs.

Erasmo 11 months ago

Yeah, it's all about finding those matching hashes!

Antonio 12 months ago

Wait, are we sure about that? Sounds too simple.

Ligia 12 months ago

Totally agree, D is the correct definition!

Elizabeth 1 year ago

Collision attacks aim to find two different inputs that hash to the same output.

I vaguely recall something about collisions in hashing, but I can't remember if it was specifically about inputs or keys. This is tricky!

I feel like collision attacks are more about the integrity of the hash function rather than breaking it into parts, so I’m leaning towards option D.

I remember practicing a question similar to this, and I think the correct answer is related to how hashes can produce the same result from different data.

I think a collision attack is about finding two different inputs that hash to the same output, but I'm not entirely sure.

Okay, I see the key requirements now - configure reachability, default routes, and floating static routes. I think I can put together the necessary configurations for each router.

Okay, let me see. I know email marketing involves things like capturing subscriber info, maintaining that data, and segmenting the audience. I think option A sounds like it covers the key elements.

Wait, I'm confused. I thought a person dying without a will would lose all of those rights. Let me re-read the question and options more closely.

Hmm, I'm not totally sure about this one. I'll have to think it through carefully.
