11.1Secure Data Transfer

This feature makes it possible for MIDlets to use safe data links to external communications partners. The specification IMP 2.0 defines two java classes with this characteristic - HTTPSConnection and SecureConnection.

The Siemens implementation follows the recommendations in IMP 2.0:

HTTPSConnection

HTTP over TLS as documented in RFC 2818 and TLS Protocol Version 1.0 as specified in RFC 2246.

SecureConnection

TLS Protocol Version 1.0 as specified in RFC 2246

Two Java Security modes exist for safe data links.

Mode 1:

Java Security not activated

No examination of the server certificate takes place when setting up the connection. The authenticity of the server certificate is not verified. (Figure 40: Mode 1 - Java Security not activated)

Mode 2 (see 11.2.1 Change to Secured Mode):

The server certificate is examined when setting up a connection. Two configurations are valid. The server certificate is identical to the certificate in the module (both certificates are self signed root certificates) or the server certificate forms a chain with the certificate of the module. Thus the authenticity of the server certificate can be examined with the help of the certificate of the module. (Figure 41: Mode 2 - Java Security activated and
