Which one of the following algorithm is not used in asymmetric key cryptography?

(A)

RSA Algorithm

(B)

Diffie-Hellman Algorithm

(C)

Electronic Code Book Algorithm

(D)

None of the above



Answer: (C)

Explanation:

RSA ALGORITHM and Diffie-Hellman Algo: These are both popular asymmetric key cryptography algorithms. RSA is used for encryption and decryption, while Diffie-Hellman is used for key exchange.

Electric Code Book (ECB) Algo: This is a symmetric key cryptography algorithm where the same key is used for both encryption and decryption. It is not suitable for asymmetric cryptography, which relies on having different keys for encryption and decryption.

None of the above: Since one option is not used in asymmetric key cryptography, this statement is not accurate.
