碩士 === 國立臺灣科技大學 === 資訊管理系 === 95 === Communicating and exchanging information with others by using third generation mobile communication (3G) is the future trend. However, the third generation mobile telecommunication system security is only limited to user-to-network or vice versa. It can not provide end-to-end protection. Mutual authentication and session key establishment can be achieved by authenticated key agreement scheme. Unfortunately, we still need to increase some modules to the current 3G system in order to implement the published low-power device key agreement schemes. Hence we use XOR, one-way hash function and one-way functions existing in the current third generation communication system to design key agreement scheme for 3G. We also propose a group key agreement scheme for the application of group communication. Our scheme will satisfy the following properties: (1) Implement on 3G system easily. (2) Achieve authentication and key agreement to ensure confidentiality of conferences. (3) Establish group key. (4) Ensure privacy of conferees’ locations. (5) Detect fake devices and avoid replay attack. (6) Has session key that is of nondisclosure, independence and integrity.
