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 SIM 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.

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.

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 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.
