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.
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 your service
provider.
To view the list of the authority or user certificates downloaded to your phone, select

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 create digital signatures with your phone if your SIM card has a security module.
The digital signature is the same as signing your name to a paper bill, contract, or other
document.
To create a digital signature, select a link on a page (for example, the title of the book
you want to buy and its price). The text to be signed is shown and may include the
amount and date.
Check that the header text is
Read
and that the digital signature icon
is shown. If
the digital signature icon does not appear, there is a security breach; do not enter any
personal data (such as your signing PIN).
