Match List I with List II. List I: (A) DES, (B) AES, (C) 3DES, (D) RSA. List II: (I) Key size 256, (II) Key size 1024, (III) Key size 56, (IV) Key size 168.

1. A(A)-(I), (B)-(II), (C)-(IV), (D)-(III)
2. B(A)-(III), (B)-(I), (C)-(IV), (D)-(II)
3. C(A)-(III), (B)-(IV), (C)-(II), (D)-(I)
4. D(A)-(IV), (B)-(II), (C)-(III), (D)-(I)

Pick an option to check yourself, or open the answer below.

Show answer & explanation

Correct answer: B. (A)-(III), (B)-(I), (C)-(IV), (D)-(II)

Explanation

DES uses a 56-bit key, AES up to 256, 3DES 168 (three DES keys), and RSA commonly 1024 bits or more.
