基于FPGA的嵌入式加密系统设计与实现
Design and Implementation of an FPGA-based Embedded Encryption System
摘要
Abstract
In response to the growing demand for efficient and secure communication in IoT and embedded devices,this study presents the design of an embedded data encryption system based on a field programmable gate array(FPGA).The system aims to provide a low-cost,highly reliable solution for secure data transmission in resource-constrained environments.The system employs a layered architecture where a host computer and an EZ-USB FX2 chip handle instruction exchange and data transfer.The FPGA acts as the core control unit and integrates a light-weight AES-128 encryption algorithm to enable hardware-level data encryption.To optimize resource utilization,the system performs encryption operations serially,and the AES algorithm's key expansion module is also optimized.Simulation and testing verified that the AES module achieves a maximum clock frequency of 181.1 MHz during encryption,ensuring efficient data processing and meeting all design requirements.关键词
