Scenario: Your company has many encrypted telecommunications links for their world-wide operations.

 Reducing the Burden of Key Distribution

Asymmetric encryption provides a secure mechanism for distributing symmetric keys without requiring physical transfer.

Public keys are used to encrypt the symmetric key, which can then be decrypted by the corresponding private key.

 Why Not Other Options?

B. Use a self-generated key: Does not address distribution challenges.

C. Use a certificate authority: Distributes certificates, not symmetric keys.

D. Symmetrically encrypt and then decrypt: Adds unnecessary complexity without addressing distribution.

 EC-Council References

Recommends hybrid encryption models that combine the strengths of symmetric and asymmetric encryption to streamline secure key distribution.
