DESCRIPTION
Enter the password for the server's identification code. This shared
public key is used by the WiMAX Device during the communication
handshake process to identify the server.
The WiMAX Device and the OMA-DM server use nonces to authenticate
each other if you select MD5 as the authentication algorithm in the
Server Auth Type field. Nonce is an abbreviation of 'number used
once'. It is normally a random or pseudo-random number applied in an
authentication protocol to protect existing communications from being
reused in 'replay attacks'.
Type up to 20 digits for the OMA-DM server nonce.
Select the encryption algorithm scheme used by the OMA-DM server to
communicate with client devices. If the scheme selected here does not
match the actual scheme used by the server, then server will challenge
the WiMAX Device to automatically update its settings.
•
None - No authentication.
•
Basic - Server ID and Password are encoded using a Basic Access
Authentication Code.
•
Digest (MD5) - Server ID and Password are encoded using a Digest
Access Authentication Code.
•
HMAC - Server ID and Password are encoded using a keyed Hash
Message Authentication Code.
Note: Make sure that the scheme selected here matches the the
Server Auth Type.
Enter the client name for the WiMAX Device.
Enter the password for the WiMAX Device's client name.
Select this to allow the WiMAX Device to periodically connect to the
OMA-DM server and check for configuration updates.
If you do not enable this feature then the WiMAX Device can only be
updated automatically when the OM-DM server initiates contact with it
and if you selected the checkbox on this screen.
Enter the time interval (in seconds) at which the WiMAX Device
connects to the OMA-DM server.
