Configuring Settings for Key Pairs and Digital Certificates
In order to  encrypt  communication with a remote device, an  encryption key  must be sent and  received over an  unsecured network
beforehand. This problem is  solved by public -key  cryptography. Public -key  cryptography ensures  secure communication by protecting
valuable information  from attacks, such as sniffing,  spoofing, and  tampering of data as it flows over a network.

Generating Key Pairs
The key  pair  required for  encrypted  communication via  Secure Sockets Layer  (SSL) can be generated  with the  machine. You  can use SSL
when accessing the  machine via  the  Remote  UI. Up to  three key  pairs can be registered on  the  machine.
Start  the Remote UI  and  log  on in System Manager Mode.  Starting the Remote UI
Click [Settings/Registration].
Click [Security  Settings]  [Key and  Certificate Settings].
Click [Generate Key].

[Key  Settings][Key  Name]
Enter up  to  24 alphanumeric  characters  for  naming the  key  pair. Set a name that  will  be easy  for  you to  find later in a list.
[Signature  Algorithm]
Select the  signature  algorithm from the  drop-down list.
[Key  Algorithm]
The algorithm used to  generate  keys is  RSA. Select the  key  length from the  drop-down list. The larger  the  number for  the
key  length, the  slower  the  communication.  However, the  security is  tighter.  
[512-bit] cannot  be selected...

Using CA-issued Key Pairs and Digital Certificates
Key pairs and  digital certificates  can be obtained from a certification  authority  (CA) for  use with the  machine. After obtaining them from a
CA, you can install and  register  key  pairs and  CA certificate files  on  the  machine by using the  Remote  UI. Make  sure  that  the  key  pair
and  the  certificate satisfy  the  requirements of the  machine (
Key  and  Certificate Operating Requirements ). You  can register  up  to
three key...

You  can only install one file on  this machine. If  another file is  already  installed,  click [Delete] [OK]  to  delete  the  previously
installed file.
Click [Browse], specify the file to install, and  click [Start Installation].
The key  pair  or CA certificate from the  computer  is  installed in the  machine. 
Register the key pair or CA certificate.
Registering a key pair
1Click [Register]  on  the right  of the key pair you want to register.
2Enter  the name  of the key pair and  password,  and...

Registering a CA certificate
Click [Register] on  the  right of the  CA certificate you want to  register.

Verifying Key Pairs and CA Certificates
Once key  pairs and  CA certificates  are  registered, you can view their  detailed information  or verify their  effective dates and  signature.
Start  the Remote UI  and  log  on in System Manager Mode.  Starting the Remote UI
Click [Settings/Registration].
Click [Security  Settings]  Click [Key and  Certificate Settings] or [CA Certificate Settings].

Using the Remote UI
You  can use a Web browser  to  operate the  machine remotely, check  the  documents waiting  to  be printed,  and  check  the  status of the
machine. You  can also  make network and  other settings for  the  machine. The "Remote  UI" starts  when you enter the  IP  address of  the
machine in your Web browser. It is  very convenient, because  it allows  you to  operate the  machine remotely without leaving your  desk  or
installing a special  application.

Starting the Remote UI
To operate the  machine remotely, start the  Remote  UI by entering  the  machine's  IP  address in your Web browser. Before starting, check
the  IP  address that  has been assigned  to  the  machine (Viewing Network Settings). If  you do not  know the  machine's  IP  address,
ask  your network administrator, or start the  Remote  UI from the  Printer Status Window  (Starting  from the Printer Status Window ).
