A Hardware Encryption and Decryption System Design

摘要

In allusion to the malpractice about pure software encryption techniques,this article puts forward an exploring thought and design process of a hardware encryption and decryption system. This system applies DES encryption algorithm,implements hardware encryption and on-line upgrade. It adopts FPGA chip and MCU as the control cores,applies microchip control technology to implement PCI busprotocol,DES algorithm and the communication with the storage device through a self-defined interface.
