is displayed during a connection, if the data
transmission between the phone and the content server is
encrypted.
Important: Even if 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. Certificates have a
restricted lifetime. If "Expired certificate" or
"Certificate not valid yet" is shown, even if the
certificate should be valid, check that the current
date and time in your device are correct.
Before changing any certificate settings, you
must make sure that you really trust the owner of
the certificate and that the certificate really
belongs to the listed owner.
There are three kinds of certificates: server certificates,
authority certificates, and user certificates. You may
receive these certificates from your service provider.
Authority certificates and user certificates may also be
saved in the security module by the service provider.
The security icon does not indicate that the data
transmission between the gateway and the content server
(or place where the requested resource is stored) is secure.
The service provider secures the data transmission
between the gateway and the content server.
