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.
