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.
