Configuring SSL Encryption
When accessing the printer using a Web Image Monitor or IPP, encrypted com-
munication can be established using SSL. When accessing the printer using an
application such as SmartDeviceMonitor for Admin, encrypted communication
can be established using SNMPv3 or SSL.
To protect data from interception, analysis, and tampering, install a server certifi-
cate in the printer, negotiate a secure connection, and encrypt transmitted data.
Important
❒ When using SSL, the optional hard disk or the data storage card are required.
❖ SSL (Secure Sockets Layer)
A To access the printer from a user’s computer, request for the SSL server cer-
tificate and public key.
B The server certificate and public key are sent from the printer to the user’s computer.
C Create shared key from the user's computer, and then encrypt it using public key.
D The encrypted shared key is sent to the printer.
E The encrypted shared key is decrypted in the machine using private key.
F Transmit the encrypted data using the shared key, and then decrypt the
data at the machine to attain secure transmission.
Note
❒ To establish encrypted communication using SSL, the printer must have
the printer and scanner functions.
