Browser security
Security features may be required for some services, for example 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.
Certificates
Certificates can be used for making secure connections through a browser or for
authenticating a downloaded application.
There are three kinds of certificates:
• authority certificates - these can be used for authenticating downloaded
applications, authenticating other authority certificates and for authenticating
servers. They may be pre-installed, or can be downloaded while browsing.
• user certificates - these are used for client authentication and/or making a digital
signature. This means that user certificates can be used to prove the identity of a
given user over a wireless connection. User certificates can also be used for
encrypting and digitally signing information, thus ensuring the confidentiality and
integrity of mobile transactions. They may be pre-installed in the security module
), or can be downloaded while browsing.
• server certificates - these may be sent by the server to the phone in case of server
authenticated (in contrast to anonymous) secure connection establishment.
When received, the validity of the certificates is checked using the local time and
authority certificates stored locally.
