Certificate management
In the Certificate management main view, you can see a list of authority
certificates that have been stored in your phone. To manage certificates,
go to Menu→ Settings→ Security→ Certif. management. Press to
see a list of user certificates, if available.
Options in the certificate management main view are:
Certificate details, Delete, Trust settings, Mark/Unmark, Help, and Exit.
Digital certificates are used to verify the origin of browser pages and
installed software. However, they can only be trusted if the origin of
the certificate is known to be authentic.
Digital certificates are needed if you want to:
• Connect to an online bank, another site, or remote server for actions
that involve transferring confidential information.
• Minimize the risk of viruses or other malicious software and be sure of
the authenticity of software when downloading and installing software.
Authority certificates are used by some services, such as banking services,
for checking signatures or server certificates or other authority certificates.
User certificates are issued to users by a Certifying Authority.
Important: Although the use of certificates makes the risks involved
in remote connections and software installation considerably smaller,
they must be used correctly in order to benefit from increased security.
The existence of a certificate does not offer any protection by itself;
the certificate manager must contain correct, authentic, or trusted
certificates for increased security to be available.
VIEWING CERTIFICATE DETAILS—CHECKING AUTHENTICITY
You can only be sure of the correct identity of a browser gateway or a
server when the signature and the period of validity of a browser gateway
or server certificate have been checked.
