Abstract


With the rapid development of Internet technology , university educational management system based on B / S structure of how to use the process to avoid illegal modifications afterwards denied that illegal interception behavior has been a direct threat to the safety of the use of the University Educational System . Modern cryptography theory are maturing and the rapid development of microelectronics design technology , which greatly enhances the the password chip design level . In this context , the digital signature technology and microelectronics in conjunction with the presentation of a USB interface hardware digital signature scheme on completion of the digital signature function key algorithm module hardware FPGA RTL level design and simulation . The subject first school in the course of the study , the overall structure of the system of the college educational management and security analysis , followed by analysis and research , we present a complete digital signature public key cryptography and private key cryptography SHA-1 algorithm , hybrid cryptosystem RSA algorithm and DES algorithm to achieve the digital signature of the program . Finally, on this basis, based on the digital signature of the USB interface chip analysis and design, to write the three focus algorithms constitute a digital signature chip module that SHA-1 algorithm module , the DES algorithm module , the RSA algorithm module Verilog HDL program simulation and Modelsim software design documents . In this paper, current FPGA design methodology and EDA design tools , design based USB interface chip that has a digital signature capability so that the USB device is both easy to use USB device compatibility , low cost and sensitive data stored encrypted with through the USB interface to provide users with sensitive data , encryption and decryption and digital signature functionality . Research projects can be a good solution to the problem of digital signature in College Teaching Management System , and can also provide a reference for the other systems, the realization of the digital signature .
