Abstract. Robots are most of their time connected to a server, a network or the cloud. When you start working with a connected - robot. You need to be fluent in SSH, SCP and KEY based authentication in order to access and manupulate your robotic systems.

SSH - Secure Shell is a cryptographic network protocol for operating network services securely over an unsecured network.

SCP - Secure Copy is a means of securley transferring files between two machines on a network. SCP uses SSH for improved security and usually it needs a password for authentication.

Key-based authentication is a kind of authentication alternative to password authentication. Instead of requiring a user's password, it is possible to confirm the client's identity by using cryptography algorithms with keys.
