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 > Settings > Security > Authority certificates or User certificates.
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 the place where the requested resource is
stored) is secure. The service provider secures the data transmission between the
gateway and the content server.
