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.
The security indicator 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.
Digital signature
You can make digital signatures with your phone 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.
