Design And Implementation Of Cipher Resource Injection System Based On Bluetooth

Crypto equipment plays an important role in ensuring information system security. And the Cipher Resource Injection, which refers to the procedure of downloading sensitive data to crypto equipment in this thesis, is the basis of various security services of the crypto equipment. Analyzing the security needs of the Cipher Resource Injection, a Cipher Resource Injection model based on Bluetooth is proposed. According to the model, the design and implementation of the Cipher Resource Injection system are introduced both from hardware and software (or firmware). At last, a prototype system is implemented.According to the security requirements of the Cipher Resource Injection channel in the FIPS (the Federal Information Processing Standards), the key of implementing Cipher Resource Injection is constructing a trusted logic interface. Under the in-depth analysis of the Cipher Resource Injection research and security needs, a Cipher Resource Injection model based on Bluetooth is built. Then security storage procedure and security transmission procedure are designed. On the basis of this, the functional structure and architecture of software and hardware are designed. The design and implementation of the Cipher Resource Injection system are introduced from both hardware and software.According to the overall design of the system, the hardware is designed, which consist of Bluetooth module, algorithm execution module and so on. Circuit design of critical modules and the structure of hardware of SOPC are researched. According to the architecture of the software and hardware, the hardware platform structure is designed and the chips used in the platform are choosen. The system circuit design details of each function module, such as hardware platform, Bluetooth security firmware and the hardware and software of SOPC, are studied in this thesis. The structure of SOPC hardware in FPGA is determined. The SRAM and SDRAM controller are designed with the actual circuit connections taken into account.On the basis of the hardware design, the implementation of critical modules in the firmware is researched. The design of the software is taken as the major research, which includes the storage encryption software, Bluetooth security firmware and the software of SOPC. In the Bluetooth firmware, the computation-intensive cryptographic algorithm is implemented by using DSP on Bluetooth chip. The method of the algorithm implementation is presented in detail in this thesis, which meets the convenience requirements of the crypto carrier in ensuring data transmission security.Finally, a prototype system of the Cipher Resource Injection is the implemented. And the critical module and resource injection data rate of the prototype system are tested. The results show that each function module works properly, and the indicators of the prototype system achieve the desired design goals. It is proved that the Cipher Resource Injection based on Bluetooth technology is feasible.
