| Summary: | 碩士 === 國立交通大學 === 資訊管理研究所 === 94 === Due to the growth of the wireless technologies, the application requirements constantly increase under the wireless network architecture. The IMT2000, issued by ITU, provides territory and satellite transmission media for mobile communications and, thus, it stands an advantageous position in terms of convenience and speed. It has more potentiality and development. However, data security and confidentiality are threatened due to data transmission on the air. Hence, the study of secure schemes is an important issue in the wireless network environment.
Access control is one of the most important parts of satellite communication, and it enforces users that are restricted to access authorized activities according to the authorization plan. Consequently, illegal users or legal users with illegal access right can be prevented to ensure the security of the system. In our research, we have implemented our algorithm and proved that it protects every resource in the system effectively, and it makes the system more flexible, too.
