 | The entire security model for MIDlet suites is new in MIDP 2.0. Unlike in MIDP 1.0, the MIDlets are no longer restricted to run only in a sandbox. Flexible mechanisms are now provided to establish a security policy for a MIDP device. The new model is extensible for use with J2ME optional packages and other APIs such as the Wireless Messaging API and the Mobile Media API. The new model can take advantage of the existing PKI infrastructure to ensure the integrity and authentication of the source of MIDlet suites. Through the protection domains, the new model enables the implementation of a variety of security policies that meet the needs of security-critical mobile applications and business models. |
