Which mode of DES is the weakest?
A.
CFB
B.
OFB
C.
ECB
D.
CDC
Explanation:
Answer C is correct; ECB is Electronic Code Book, the simplest form of DES. It uses no initialization vector or chaining.Incorrect Answers and Explanations: A, B, and D: Answers A, B, and D are incorrect. Cipher Feedback, Output Feedback, and Cipher Block Chaining all use initialization vectors and chaining or feedback.
