Digital signatures
You can sign a contract with your phone by entering
a digital signature PIN as if signing with a pen on
paper. Digital signature records can be traced back
to your private key through a certificate that is used
for signing a contract.
All transactions (signed contracts) made with your
phone when browsing are stored in your phone.

Trusted certificates and Client certificates
To establish a secure connection when using
certain WAP services, for example banking or
WAP shopping, you need certificates in your phone.
The different types of certificates are as follows:
1. Server certificates are used to identify a WAP gateway
to the phone and to show that it is certified by a trusted
authority. The server certificate is checked against
trusted certificates that are stored in the phone or in
a security module. If the phone cannot verify the
identity of a server, you are given the option to
terminate or continue the connection.
2. Trusted certificates are used to verify the WAP
gateway that you are trying to connect to. Your
phone may already contain trusted certificates
when you buy it. If you have a security module
it may also contain trusted certificates.
3. Client certificates are located in a security module
together with your private keys. Client certificates
can be used to present your identity to a bank or
other services. They can also be used for
digital signatures.
