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.
