| Abstract: | The article analyzes Secure Hash Algorithm deeply,at the same time the process of the Secure Hash Algorithm is put up,at last it introduces an encrypted authentication system application based on SHA-1.The whole FPGA authentication system communicate with the encrypted chip of the DS28E01through the 1-wire bus.8-bit micro-controller Pico Blaze is designed by Xilinx FPGA,which is adopted as the hose kernel.Finally,the experiment can achieve the course of the encrypted authentication system. |
