Huawei H12-711_V4.0 Exam - Topic 6 Question 58 Discussion

Actual exam question for Huawei's H12-711_V4.0 exam
Question #: 58
Topic #: 6
[All H12-711_V4.0 Questions]

DES is a stream encryption algorithm, because the cipher capacity is only 56 bits, so it is not enough to deal with the weakness of insufficient security, and later 3DES was proposed.

I think 3DES is still not enough for modern security needs.

I'm a bit confused; I thought DES was a block cipher, but the question mentions stream encryption. Maybe I need to review that section again.

I feel like I saw a practice question about DES and its weaknesses, but I can't quite remember if it was classified as a stream or block cipher.

I think the statement is true because I recall that 3DES was introduced to strengthen DES due to its vulnerabilities.

I remember studying that DES has a 56-bit key, but I'm not sure if it was specifically called a stream cipher.

This seems like a straightforward true/false question based on the information provided. The passage clearly states that DES has a 56-bit cipher capacity, which is not enough for modern security needs, so the statement that "DES is a stream encryption algorithm" must be true.

I'm a little confused by this question. The passage talks about the limitations of DES, but I'm not sure how that relates to whether it's a stream encryption algorithm or not. I'll have to re-read the question and passage more closely to figure this out.

Okay, I think I've got it. The passage is saying that DES is not secure enough because of its 56-bit cipher, so 3DES was created to address that weakness. So the statement "DES is a stream encryption algorithm" must be true.

Hmm, I'm a bit unsure about this one. The passage mentions the weakness of DES due to its 56-bit cipher capacity, but I'm not sure if that directly means the statement "DES is a stream encryption algorithm" is true or false. I'll have to think this through carefully.

This question seems straightforward. The passage clearly states that DES has a 56-bit cipher capacity, which is not enough for modern security needs, so 3DES was developed as a solution.

I bet the person who came up with 3DES was just trying to mess with us. Talk about security through obscurity!

56 bits? That's like security from the Stone Age. 3DES is definitely the way to go these days.
