Siemens 5881 User Manual

Diffie-Hellman is the key exchange system used for authentication in the establishment and maintenance of 
SSH connections. The Key exchange requires a Public key and a Private key. This key pair can either be 
loaded from a source file or generated by the router. This section describes how to generate the key pair on 
the router. Refer to the section titled 

 for details on loading the key pair from a file.

Executing this function will generate new keys. This function may take in excess of one hour to complete. 
When started, the user will be redirected to a status page that is refreshed every 60 seconds. The status page 
indicates whether the task is running. When the task is no longer running, results are displayed. 

Once the task is started, you can close this page and the Keygen function will continue. You can reopen it 
anytime by clicking Key Generator Status on the left navigation pane of the Secure Shell (SSH) Configuration 
List page.

To generate the key pair on the router:

1. Click Key Generator on the left navigation pane of the Secure Shell (SSH) Configuration List page. This 

displays the Generate Public-Private Key Pair page.

2. Click Generate to generate the keys.

3. To monitor the key generation progress, click Key Generator Status from the left navigation pane of the 

Secure Shell (SSH) Configuration List page.
