Using a Digital Certicate

About Digital Certication

❏ CA-signed Certicate

is is a certicate signed by the CA (Certicate Authority.) You can obtain it to apply to the Certicate

Authority. is certicate certies the existence of the printer is and used for SSL/TLS communication so that

you can ensure the safety of data communication.

When it is used for SSL/TLS communication, it is used as a server certicate.

When it is set to IPsec/IP Filtering or IEEE802.1x communication, it is used as a client certicate.

❏ CA Certicate

is is a certicate that is in chain of the CA-signed Certicate, also called the intermediate CA certicate. It is

used by the web browser to validate the path of the printer's certicate when accessing the server of the other

party or Web Cong.

For the CA Certicate, set when to validate the path of server certicate accessing from the printer. For the

printer, set to certify the path of the CA-signed Certicate for SSL/TLS connection.

You can obtain the CA certicate of the printer from the Certication Authority where the CA certicate is

issued.

Also, you can obtain the CA certicate used to validate the server of the other party from the Certication

Authority that issued the CA-signed Certicate of the other server.

❏ Self-signed Certicate

is is a certicate that the printer signs and issues itself. It is also called the root certicate. Because the issuer

certies itself, it is not reliable and cannot prevent impersonation.

Use it when making the security setting and performing simple SSL/TLS communication without the CA-

signed Certicate.

If you use this certicate for an SSL/TLS communication, a security alert may be displayed on a web browser

because the certicate is not registered on a web browser. You can use the Self-signed Certicate only for an

SSL/TLS communication.
