Security indicator
If the security indicator is displayed during a WAP connection, the data transmission between the
phone and the WAP gateway or WAP server (identified by the IP address in the Edit active service
settings) is encrypted.
However, the security indicator does not indicate that the data transmission between the gateway and
the content server (the location where the requested resource is stored) is secure. It is up to the service
provider to secure the data transmission between the gateway and the content server.
Security module
The security module provides security services for WAP related applications, and allows the use of the
phones digital signature functionality. If present, the security module is in the SIM card as an optional
service of your service provider. The security module helps to determine whether the card content has
not been maliciously read or modified. It can contain certificates, as well as private and public keys to
operate the certificates. The certificates are stored in the security module by SIM card issuer or service
provider.

Digital signature

With the digital signature functionality you can, for example, digitally sign a bill or a financial
contract. The signature can be traced back to you via the private key and the associated certificate that
was used to perform the signature, so signing using the digital signature is the same as signing your
name to a paper bill, contract or other document.
A digital signature is initiated by a code embedded in a WAP page. Select a link, for example, the title
of the book you want to buy and its price. The digital signature procedure starts and shows the text to
sign. At this point the header text is Read and the digital signature icon is shown.
