The most important symmetric algorithms, all of which are block ciphers, are the DES, triple DES, and the __________.
A) SHA
B) RSA
C) AES
D) DSS

Question

Quizplus · Accepted Answer

The correct answer is C) AES (Advanced Encryption Standard). This is because AES is currently the most widely used symmetric encryption algorithm for its efficiency, speed, and security. DES and triple DES are outdated and not as secure as AES, while SHA and RSA are not symmetric encryption algorithms, but rather hash and asymmetric encryption algorithms, respectively.
