service provider secures the data transmission between the gateway and the
content server.
Security certificates may be required for some services, such as banking
services. You are notified if the identity of the server is not authentic or if you
do not have the correct security certificate in your device. For more
information, contact your service provider.
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.
