Password authentication works as follows: The client sends a password
■
authentication request carrying the encrypted username and password to the
server. The server decrypts the request to obtain the username and password in
plain text, and matches the username and password against those configured
on itself. Then, it returns the authentication result according to the matching
result.
RSA authentication works as follows: The client sends an RSA authentication
■
request carrying the username, public key and public key algorithm to the
server. The server checks the validity of the public key. If the key is invalid, the
server returns an authentication failure message directly; otherwise, the server
authenticates the client and returns the authentication result to the client.
4 Session request stage. After successful authentication, the client sends session
request messages to the server. The server processes the request messages.
5 Interactive session stage. Both ends exchange data till the session ends.
