Trust extended object-oriented security model

With the development of Internet and its application, mobile code technique has become a hot research area in latest years. Because mobile codes have strong ability of being independent, autonomic, mobile, and mixed with data, it's ineffective to handle their security issues with traditional access control systems. Inspired by the integration of trusted computing and object-oriented method, we propose a new trust extended object-oriented security model-TEOOSM, which can be applied to the access control system of mobile codes. Our model encapsulates the code and data, utilizes the trusted status measurement, and then effectively protects platforms, codes and data from being destroyed by malicious codes or systems.
