Design And Implementation Of The HF Communication Control Board

In this paper, the research content is derived from scientific research project "Short-Wave frequency selection and link establishment system technology research". According to the working principle and security requirements of the system, we focuses on the design and implementation of the hardware platform of the communication control board and system authentication scheme in this system. The main work and achievements of this paper are as follows:1?Short-Wave frequency selection and link establishment system is studied in the paper. Firstly, aiming at the design requirements and targets of the system, the general scheme of the system is studied, and the whole communication system composition block diagram is given; secondly, the role of link establishment module of the HF communication in the whole system is studied, and the design of hardware structure diagram is given; finally, we study the part of the HF communication control board in the whole system, focus on illustrating the reasons of choosing the TM4C129 microprocessor as the main control chip for the whole hardware platform, and design the hardware structure of its basic block diagram.2 ? The hardware platform of the HF communication control board is designed, implemented and verified. In this system, the communication control board is mainly responsible for link establishment communication protocol. Aiming at the design requirements and targets, design and implementation of the hardware platform basing on ARM Cortex-M4 are researched. Firstly, the basic characteristics of the ARM Cortex-M4 series processors and the TM4C129 microprocessor are studied; secondly, the principle of selecting key components and the design process of peripheral circuit in the controlling board are presented; then hardware PCB design, debugging and implementation of the communication control board are illustrated; at last, that the controlling hardware platform of the HF communication can satisfy the expected target and the design requirements of the system is verified through the test and actual application.3?The identity authentication scheme of the HF communication control board is designed, implemented and verified. Aiming at the requirements of protecting the intellectual property rights of the communication control board, the design and implementation of the identity authentication scheme basing on FPGA is researched. It begins with analyzing the variously possible safety hazards of the embedded system and defending method against diverse attacks; secondly, the author gives the overall design scheme of identity authentication, and has analyzed the principle of selecting the FPGA chip processor; then the author uses the Verilog HDL language programming to realize the whole identity authentication scheme, and uses the Model Sim software simulating various modules of the proposed scheme; at last, the correctness of the identity authentication scheme is verified in the test...
