Security module

The security module improves security services for applications requiring a
browser connection, and allows you to use a digital signature. The security
module may contain certificates as well as private and public keys. The
certificates are saved in the security module by the service provider.
To view or change the security module settings, select Menu > Settings >
Security > Security module settings.
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.
