BCS CISMP-V9 Exam - Topic 1 Question 99 Discussion

Actual exam question for BCS's CISMP-V9 exam
Question #: 99
Topic #: 1
[All CISMP-V9 Questions]

Which algorithm is a current specification for the encryption of electronic data established by NIST?

Show Suggested Answer Hide Answer
Suggested Answer: B

The Advanced Encryption Standard (AES) is the current specification for the encryption of electronic data established by the National Institute of Standards and Technology (NIST). AES is a symmetric block cipher that can encrypt (encipher) and decrypt (decipher) information, converting data to an unintelligible form called ciphertext and back to its original form, plaintext. The AES algorithm is capable of using cryptographic keys of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits.It was selected by NIST as a Federal Information Processing Standard (FIPS) to protect electronic data and is widely recognized and used for secure data encryption1.

I thought DES was outdated, so it must be AES, right? I hope I’m not confusing it with something else!

I'm a bit confused on this one. I know DES used to be the standard, but I think that's been replaced by something newer. I'm going to guess B, AES, since that sounds like the most up-to-date option.

AES, definitely AES. I remember learning about that in my computer security class as the NIST-approved encryption algorithm.

Okay, let me think this through. NIST is the National Institute of Standards and Technology, so they would be responsible for setting encryption standards. Based on that, I'm going to go with B, AES.
