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 options 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. You can also download trusted certificates from Sony Ericsson Mobile Internet or other WAP pages.
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.
