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.

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 place where the requested resource is stored)
is secure. The service provider secures the data transmission between the
gateway and the content server.
