Question

Symmetric algorithms have drawbacks in these areas (Choose 2):

A). Key Management
B). Preserving Confidentiality
C). Non-repudiation features
D). Speed

Answer 1

Symmetric algorithms have drawbacks in key management and speed.

Step-by-step explanation:

Symmetric algorithms, such as AES (Advanced Encryption Standard), have several drawbacks in certain areas. Two of the areas where symmetric algorithms have drawbacks are:

1. Key Management: Symmetric algorithms require both the sender and the receiver to have the same secret key, which can be a challenge to manage securely and distribute to all parties involved. If the key is compromised, all encrypted data can be decrypted.
2. Speed: Symmetric algorithms are generally faster than asymmetric algorithms but may not be as fast as some newer encryption techniques. They can become a bottleneck in high-speed data transmission scenarios.
