■ Browser security
Security features may be required for some services, such as online banking or
shopping. For such connections you need security certificates and possibly a
security module, which may be available on your SmartChip card. For more
information, contact your service provider.
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 sett.
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.
