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.
To view the list of the authority or user certificates downloaded into your device,
select Menu > Settings > Security > Authority certificates or User certificates.
is displayed during a connection, if the data transmission between the
device 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.
Digital signature
You can make digital signatures with your device if your SIM card has a security
module. Using the digital signature can be the same as signing your name to a
paper bill, contract, or other document.
