Answer:
RDP
SSH
Step-by-step explanation:
RDP and SSH can both be used for remote encrypted communication. RDP protocol( called remote desktop protocol) is owned by Microsoft. It allows it's user access to the network through a GUI RDP software that allows you to connect to another computer on the network, the client server. RDPs operate over encrypted channels and is therefore secure.
SSH(called secure shell protocol) is used on Unix like OS systems to connect over unsecured network. SSH uses cryptographic encryption that increases security for it's client-server architecture. It's an improved version of RSH and Telnet which didn't make use of encryption when sending data over the network.
