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.

PGP? Really? That's more of a whole package, not just an algorithm. I'd go with B, AES.

I remember studying that AES is recommended by NIST for encryption, so I'll go with B) AES.

I'm not sure, but I think AES makes sense because it's widely used and considered secure.

Hmm, I'm pretty sure it's DES. Isn't that the classic NIST encryption standard?

Really? I always thought DES was the go-to for NIST encryption.

I think you're mistaken, it's actually AES.

AES, of course! NIST has been using it for years. Easy choice.
