Question
Which one of the following is not a mode of operation for the Data Encryption Standard?Question 3Answera.AESb.OFBc.CBCd.CFB
Solution
The answer is a. AES. This is because AES (Advanced Encryption Standard) is not a mode of operation but rather a separate encryption standard. The other three options - OFB (Output Feedback), CBC (Cipher Block Chaining), and CFB (Cipher Feedback) are all modes of operation used in the Data Encryption Standard (DES).
