Exam 312-50v11 topic 1 question 53 discussion

I would say : D. Asymmetric cryptography is computationally expensive in comparison. However, it is well-suited to securely negotiate keys for use with symmetric cryptography.

D . Supporting both types of algorithms allows less-powerful devices such as mobile phones to use symmetric encryption instead.

The answer is D

D is the correct answer.

it is D

[TLS] uses a symmetric key for bulk encryption, an asymmetric key for authentication and key exchange, and message authentication codes for message integrity Appendix A, p.3273/3257

One of the advantages of using both symmetric and asymmetric cryptography in SSL/TLS is that asymmetric cryptography is used for secure key exchange and authentication, while symmetric cryptography is used for data encryption and decryption. Asymmetric cryptography is computationally expensive, so using it only for the initial key exchange and then switching to faster symmetric cryptography for actual data encryption provides a balance between security and performance. This approach allows secure negotiation of session keys, which are then used for symmetric encryption, which is faster and more efficient for data transmission.

Why is the answer 'A' and not 'D'?

D. Asymmetric cryptography is computationally expensive in comparison. However, it is well-suited to securely negotiate keys for use with symmetric cryptography.

D. Asymmetric cryptography is computationally expensive in comparison. However, it is well-suited to securely negotiate keys for use with symmetric cryptography.

Answer: D In SSL/TLS, asymmetric cryptography is used during the initial handshake to securely exchange and negotiate session keys. Once the keys have been exchanged, symmetric cryptography is used for encrypting the data transmitted between the client and server. Symmetric encryption is more efficient and faster than asymmetric encryption, making it more suitable for bulk data encryption during the communication session.

Is correct

Asymmetric cryptography is computationally expensive in comparison. However, it is well-suited to securely negotiate keys for use with symmetric cryptography.

Seems the most appropriate

D, gives benefits for both high and low computing power machines.

Asymmetric Cryptography is typically used to transmit Symmetric keys due to the high resource cost associated with Asymmetric. No current devices fails between either.
