11 Java Security

The Java Security Model follows the specification of IMP 2.0 but does not integrate the

protection domain concept. The protection domain concept is not needed. If the software is

enabled, all domains are available.

Java Security is divided into two main areas:

• secure MIDlet data links (HTTPS, Secure Connection) (see chapter 11.1)

• execution of signed MIDlets (see chapter 11.2 Execution Control )
