9
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 pub-
lic 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.
SSL (Secure Sockets Layer) Encryption
This can be specified by the network administrator.
To protect the communication path and establish encrypted communication,
create and install the server certificate.
There are two ways of installing a server certificate: create and install a self-cer-
tificate using the printer, or request a certificate from a certificate authority and
install it.
Configuration flow (self-signed certificate)
A
Creating and installing the server certificate
Install the server certificate using Web Image Monitor.
B
Enabling SSL
Enable the
[
SSL/TLS
]
setting using Web Image Monitor.
Configuration flow (certificate issued by a certificate authority)
A
Creating the server certificate
Create the server certificate using Web Image Monitor.
The application procedure after creating the certificate depends on the cer-
tificate authority. Follow the procedure specified by the certificate author-
ity.
B
Installing the server certificate
Install the server certificate using Web Image Monitor.
C
Enabling SSL
Enable the
[
SSL/TLS
]
setting using Web Image Monitor.
Creating and Installing the Server Certificate (Self-Signed Certificate)
Create and install the server certificate using Web Image Monitor.
Note
To confirm whether SSL configuration is enabled, enter https://(printer’s-ad-
dress) in your Web Image Monitor’s address bar to access this printer. If the
“The page cannot be displayed” message appears, check the configuration as
the SSL configuration is invalid.
