The following table summarizes how a secure connection is established between two remote 
hosts. 

Figure 290   How SSH Works

1 Host Identification

The SSH client sends a connection request to the SSH server. The server identifies itself 
with a host key. The client encrypts a randomly generated session key with the host key 
and server key and sends the result back to the server. 

Encryption Algorithm

The Encryption Algorithm field is used to encrypt communications between 

the ZyWALL and the Vantage CNM server. Choose from None (no 

encryption), DES or 3DES. The Encryption Key field appears when you 

select DES or 3DES. The ZyWALL must use the same encryption algorithm 

as the Vantage CNM server. 

Encryption Key

Type eight alphanumeric characters ("0" to "9", "a" to "z" or "A" to "Z") when 

you choose the DES encryption algorithm and 24 alphanumeric characters 

("0" to "9", "a" to "z" or "A" to "Z") when you choose the 3DES encryption 

algorithm. The ZyWALL must use the same encryption key as the Vantage 

CNM server.
