DESCRIPTION
Enter the password for the server's identification code. This shared
public key is used by the MAX208M2W Series during the communication
handshake process to identify the server.
The MAX208M2W Series 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 MAX208M2W Series 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 MAX208M2W Series.
Enter the password for the MAX208M2W Series's client name.
The MAX208M2W Series and the OMA-DM server use nonces to
authenticate each other if you select MD5 as the authentication
algorithm in the Client Auth Type field.
Type up to 20 digits for the OMA-DM client nonce.
Select this to allow the MAX208M2W Series to periodically connect to
the OMA-DM server and check for configuration updates.
If you do not enable this feature then the MAX208M2W Series 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 MAX208M2W Series
connects to the OMA-DM server.
