Implementing Secure Solutions with Virtual Private Networks (SVPN) — Question 93

What are two functions of ECDH and ECDSA? (Choose two.)

Answer options

• A. nonrepudiation
• B. revocation
• C. digital signature
• D. key exchange
• E. encryption

Correct answer: C, D

Explanation

ECDH (Elliptic Curve Diffie-Hellman) is utilized for secure key exchange, while ECDSA (Elliptic Curve Digital Signature Algorithm) is employed for creating digital signatures. The other options, such as nonrepudiation and revocation, are not direct functions of these algorithms, and encryption is not a primary purpose of either ECDH or ECDSA.
