将以下对称块密码与相应的块和密钥大小匹配：

List – I	List – II
(a) DES	(i)block size 64 and key size ranges between 32 and 448
(b) IDEA	(ii) block size 64 and key size 64
(c)BLOW FISH	(iii)block size 128 and key sizes 128, 192, 256
(d)AES	(iv)block size 64 and key size 128	codes: (a) (b) (c) (d) (1) (iv) (ii) (i) (iii) (2) (ii) (iv) (i) (iii) (3) () () () () (4) (iv) (ii) (iii) (i) (A) (1) (B) (2) (C) (3) (D) (4)Answer: (B) Explanation: Data Encryption Standard(DES) block cipher uses block size 64 and key size 64 International Data Encryption Algorithm (IDEA) uses block size 64 and key size 12. BLOW FISH is the relacement for DES or IDEA, it uses block size 64 and key size ranges between 32 and 448 Advanced Encryption Standard (AES) uses block size 128 and key sizes 128, 192, 256 So, option (B) is correct.
