Why is using ECDHE_ECDSA stronger than using RSA?
A. ECDHE_ECDSA provides both data authenticity and confidentiality.
B. ECDHE_ECDSA uses a much larger key size.
C. ECDHE_ECDSA uses a pseudorandom function to generate the keying materials.
D. If the server’s private key is later compromised, all the prior TLS handshakes that are done using the cipher suite cannot be compromised.
