Discuss ISC2 SSCP Exam Topic 6 Question 118

What can be defined as secret communications where the very existence of the message is hidden?

AClustering

BSteganography

CCryptology

DVernam cipher

Suggested Answer: B

Steganography is a secret communication where the very existence of the message is hidden. For example, in a digital image, the least significant bit of each word can be used to comprise a message without causing any significant change in the image. Key clustering is a situation in which a plaintext message generates identical ciphertext messages using the same transformation algorithm but with different keys. Cryptology encompasses cryptography and cryptanalysis. The Vernam Cipher, also called a one-time pad, is an encryption scheme using a random key of the same size as the message and is used only once. It is said to be unbreakable, even with infinite resources.

C) Cryptology is broader, but B is specific to hiding messages.

I was torn between B and C, but B feels more accurate.

Tula 2 months ago

Agreed! Steganography is all about concealing the existence of the message.

Johana 2 months ago

I think it's B) Steganography. It hides the message itself.

Hillary 2 months ago

Totally agree with B! It's fascinating how it works.

B is right, but A) Clustering is related to data too.

Joaquin 2 months ago

Wait, I never heard of steganography before. Sounds cool!

Casandra 3 months ago

I thought it was C) Cryptology. Isn't that about codes?

Micah 3 months ago

Definitely B) Steganography. It's all about hiding messages!

I’m a bit confused between steganography and cryptology. They both deal with secret messages, but I think steganography is specifically about hiding the existence of the message.

Ashanti 3 months ago

I feel like I’ve seen a question like this before, and I think it was about steganography too. It’s definitely about hiding messages, right?

Aja 3 months ago

I remember studying cryptology, but that’s more about encoding messages rather than hiding them. So, I guess it’s not the right choice.

I think the answer might be B) Steganography, but I’m not entirely sure. It sounds familiar from my notes.
