Match List I with List II:

List I	List II
(A) DES	(I) Key size - 256
(B) AES	(II) Key size - 1024
(C) 3 DES	(III) Key size - 56
(D) RSA	(IV) Key size - 168

Choose the correct answer from the options given below:

DES stands for Data Encryption Standard.

DES uses a $56$ bit key.

So,

$(A)-(III)$

AES stands for Advanced Encryption Standard.

AES supports different key sizes like $128$, $192$ and $256$ bits. In the given options, AES is matched with key size $256$.

So,

$(B)-(I)$

3 DES means Triple DES.

It applies DES three times, so its effective key size is commonly taken as $168$ bits.

So,

$(C)-(IV)$

RSA is a public key cryptographic algorithm.

In the given options, RSA is matched with key size $1024$.

So,

$(D)-(II)$

Final matching is:

$(A)-(III), (B)-(I), (C)-(IV), (D)-(II)$
