Certificates
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.
To view the list of the authority or user certificates downloaded into your phone,
select Menu > Web > Settings > Security settings > Authority certificates or
User certificates.
The security indicator
is displayed during a connection, if the data transmission
between the phone and the content server is encrypted.
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.
