CompTIA Security+ study material · question 608 of 611

Besides forward secrecy, what did TLS 1.3 improve about the handshake?

  1. It allowed renegotiation mid-session
  2. It removed the need for certificates
  3. It added support for compression
  4. It reduced the common case to one round trip and encrypted more of the exchange
Show the answer

Answer: D. It reduced the common case to one round trip and encrypted more of the exchange

Fewer round trips lowers latency and encrypting more of the handshake reduces what a passive observer learns.
