【Abstract】 With the development of GPS technology, miniaturization and modularization of the GPS equipments have created good conditions for extensive application of GPS. However, the safety and controllability of equipments and information in the communication system have become the important problems. The safety and the controllability of equipments and information in complicated circumstance can be realized by using location information based on GPS encryption. Two examples in realizing decryption area controllability and safety controllability of equipment by using GPS are described in this paper, and some problems , unsolved by common encryption , can be solved now by this method.更多还原
