Question

Quizplus · Accepted Answer

Digital certificates are used to authenticate the identity of a client or a server in a network. In transport mode, the data is encrypted and decrypted without changing the original IP header, whereas in tunnel mode, a new IP header is added to the encrypted data. Therefore, digital certificates are required in transport mode to ensure the authenticity of the client PCs. Tunnel mode is used for VPN connections between networks, and the digital certificates used in this mode are to authenticate the tunnel endpoints, not the client PCs.
