Eccouncil ECSS Exam - Topic 6 Question 91 Discussion

Actual exam question for Eccouncil's ECSS exam

Question #: 91
Topic #: 6

Kevin, a security team member, was instructed to share a policy document with the employees. As it was supposed to be shared within the network, he used a simple algorithm to encrypt the document that just rearranges the same characters to produce the ciphertext.

Identify the type of cipher employed by Kevin in the above scenario.

ATransposition cipher

BStream cipher

CBlock cipher

DSubstitution cipher

Wow, I didn't expect that! Thought it was more complex.

Pretty sure it's A, but I can see the confusion.

Wait, are we sure it's not a substitution cipher?

Agreed, rearranging characters is classic transposition.

That's definitely a transposition cipher!

I keep mixing up transposition and substitution ciphers. Is it possible that this could be a substitution cipher too?

This sounds like a similar question we practiced where we discussed how transposition ciphers work. I feel confident it's A.

I'm not entirely sure, but I remember something about stream ciphers being more about continuous data rather than rearranging characters.

I think this is a transposition cipher since it just rearranges the characters without changing them.

Okay, I think I've got it. Since the question specifies that the algorithm just rearranges the characters without changing them, that rules out substitution. It's most likely a transposition cipher.

Hmm, I'm a bit confused. The question says the algorithm "rearranges the same characters," but that could also describe a substitution cipher. I'll have to think this through carefully.

This seems like a straightforward question. The key details are that the algorithm just rearranges the characters, so it's likely a transposition cipher.

Transposition cipher, got it. This is a classic crypto question, and the description matches that type of cipher. I feel pretty confident about this one.

Haha, I bet Kevin got this idea from a cartoon he watched. 'Just rearrange the letters, that'll keep 'em safe!' Clearly, he needs to brush up on his cryptography skills.

Hold on, did Kevin really use a simple algorithm? Sounds like he might have just swapped the characters around without any real encryption. What a slacker!

He should have used a more secure method like a block cipher instead.

Kevin probably used a substitution cipher, just rearranging characters.

Hmm, I'm not so sure. Rearranging characters could also be a substitution cipher, where each character is replaced with another. I'll have to think this one through a bit more.

Ah, I think Kevin used a transposition cipher. The question mentions he just rearranged the characters to produce the ciphertext, which is the defining characteristic of a transposition cipher.
