Browser security

Security features may be required
for some services, such as banking
services or shopping on a site. 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 can contain
certificates as well as private and
public keys. The security module may
improve the security services for
applications requiring browser
connection, and allows you to use a
digital signature. The certificates are
saved in the security module by the
service provider.
