Browser security
Security features may be required for some services, such as banking services or
online 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 can contain certificates as well as private and public keys. The
purpose of the security module is to improve security services for applications
requiring browser connection, and it allows you to use a digital signature. The
certificates are saved in the security module by the service provider.
Select Menu > Web > Settings > Security settings > Security module settings
and from the following options:
Security module details—to show the security module title, its status,
manufacturer, and serial number
Module PIN request—to set the phone to request the module PIN when using
services provided by the security module
Change module PIN—to change the module PIN, if allowed by the security module
Change signing PIN—to change the signing PIN
See also "Access codes," p. 7.
Certificates
There are three kinds of certificates: server certificates, authority certificates, and
user certificates.
• The phone uses a server certificate to create a connection with improved security
to the content server. The phone receives the server certificate from the service
provider before the connection is established and its validity is checked using
the authority certificates saved in the phone. Server certificates are not saved.
The security indicator is displayed during a connection if the data
transmission between the phone and the content server is encrypted.
