768-bit RSA Key = This key size provides normal security and is the default selection. It requires

approximately 2 to 4 times more processing than the 512-bit key.

1024-bit RSA Key = This key size provides high security. It requires approximately 4 to 8 times more

processing than the 512-bit key.

Configuration | System | Management Protocols | SSH

This screen lets you configure the VPN 3002 SSH (Secure Shell) protocol server. SSH is a secure

Telnet-like terminal emulator protocol that you can use to manage the VPN 3002, using the Command

Line Interface, over a remote connection.

The SSH server supports SSH1 (protocol version 1.5), which uses two RSA keys for security. All

communication over the connection is encrypted. To provide additional security, the remote client

authenticates the server and the server authenticates the client.

At the start of an SSH session, the VPN 3002 sends both a host key and a server key to the client, which

responds with a session key that it generates and encrypts using the host and server keys. The RSA key

of the SSL certificate is used as the host key, which uniquely identifies the VPN 3002 See
