摘　　要：硬件加解密技术具备安全性高、运算速度快和稳定性强等优势,但也存在加密算法固定、灵活性欠佳以及修改部署成本高昂等问题。基于国产RK3568主控芯片与开源鸿蒙操作系统,就充电场站对加密安全的需求,将不同速率及算法支持的加解密芯片进行集成,并设计一套基于国产主控芯片RK3568为调度核心,依据需求自适应动态进行加解密芯片调度的优化方案。实验验证及试点表明,系统运行状态良好,可自由选择切换加解密方案,并能够并行处理加解密需求,进一步提高系统效率。Hardware encryption and decryption technology offers advantages such as high security,fast operation speed,and strong stability.However,it also has limitations,including fixed encryption algorithms,lack of flexibility,and high costs for modification and deployment.Based on the domestic RK3568 main control chip and the open-source HarmonyOS,this study addresses the encryption security requirements of charging stations by integrating encryption and decryption chips that support different rates and algorithms.A dynamic and adaptive optimization scheme was designed,with the RK3568 chip as the core scheduler,to dynamically allocate encryption and decryption tasks based on demand.Experimental verification and pilot tests demonstrate that the system operates efficiently,allowing for flexible switching between encryption and decryption schemes while processing multiple encryption and decryption tasks in parallel,thereby further improving system efficiency.
