A IP Core Interface Design of the data encryption system and Modbus Protocol
JIANG Cun-bo,SUN Chao-hua,TANG Bo,FU Han,DU Ting-ting (Electrical Engineering Department of GUT Guilin 541004 China) 【Abstract】In this paper,the author gives the iterative algorithm of the DES and Modbus Protocol in the hardware description language, with the requirements of the Distributed control system for transmission of data encryption, and completes the IP core design of the DES algorithm and the Modbus protocol with the help of the Verilog HDL Language and the FPGA chip EP2C5T144C6. at last,the test results to the network control module under the control of C8051F020 processor and the IP core chip show that this method can better meet the need of the real-time data encryption communication.
