RDS Plug-in

failure recovery

measures

In the event that there is a physical failure on the server hosting iWEMC RDS

Plug-in, the settings for the RDS Plug-in can be restored with the XML

configuration file. Therefore it is important for the server administrator to

maintain a backup of the configuration file.

However, the jam log and alarm log kept by the RDS Plug-in are not included

in this configuration file and may be lost.

Authentication

Procedures

Server Authentication

The UGW utilizes SSL authentication together with application

authentication. The RDS Plug-in will only transmit data to the UGW server

using these methods.

1) SSL Authentication

SSL Authentication is performed according to the following procedures.

Please note the following steps describe the SSL protocol and are not specific

to Canon technology.

• “Root Certificates” published by Verisign are packaged with the RDS

Plug-in. After installing the RDS Plug-in, the certificate must be

registered on the UI of the RDS Plug-in.

• When the RDS Plug-in starts communicating, it receives the “Server

Certificate” published by Verisign from the UGW by HTTPS.

• The RDS Plug-in compares the “Server Certificates” with the “Root

Certificates”.

• If these certificates match, the RDS Plug-in successfully authenticates

the other communicating party as the UGW server.

• The encryption method is negotiated using HTTPS, afterwards,

HTTPS communications begin and the data is encrypted

2) Application level authentication

On the application level, the UGW server will be authenticated by the RDS

Plug-in. Communication will proceed only when the UGW has been

successfully authenticated. This further ensures that the RDS Plug-in will not

communicate with any destination other than the UGW.
