Digital Signature In The Educational Administrative System Of College

Along with the rapid development of Internet technology,How to avoid illegal surveillance, illegal modification in educational administrative system of college based on Browser/Serve structure becomes an important problem. Rapid development of modern electronic system integration technology and gradual perfect of crip theory provides strong suppor to the birth of security chip.In this context, This article combines Digital Signature Technology and microelectronics to present a kind of digital signature Chip based on USB interface technology. At the same time This article complete the RTL-level design and simulation for the key module.Research was done on public-key cryptosystem and private-key cryptosystem A new systerm of the cryptosystem was designed based on SHA-l,DES and RSA security. This article write a program based on SHA-1,DES and RSA modules using Verilog HDL language. And through the Modelsim software to design documents are simulated.This article combining the FPGA design method and EDA tools presents a kind of digital signature Chip based on USB interface technology.The digital signature Chip based on USB interface technology have their own characteristics,for example easy touse and Low cost,it can provide digital signature and data encryption. This research can solve the digital signature problem of Educational Administrative System and it can provide reference for other digital signature system.
