Certificates
The phone supports three kinds of certificates: server certificates, authority
certificates, and user certificates. You may receive these certificates from a
service provider. Authority certificates and user certificates may also be saved
in the security module by the service provider. For details and availability,
contact your service provider.
When using a server certificate, the security icon
connection if the data transmission between the phone and the gateway (identified
by the IP address in the Edit active service settings) is encrypted. However, the
security icon does not indicate that the data transmission between the gateway
and the content server (place where the requested resource is saved) is secure. It is
up to the service provider to secure the data transmission between the gateway and
the content server.
Important: The use of certificates makes the risks involved in remote
connections and software installation considerably smaller, but 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.
