摘　　要：为了解决无安全设计的物联网以及传统无通信功能的设备无法保证数据安全传输的问题,采用了一种软硬件协同加密的数据加密方案,将其部署在数据传输单元之中。该设计基于国密算法与LKT4305加密芯片,内置EC600N-CN通信模块,采用软硬件协同加密的机制保障用户数据安全;随着数据的读取调用伪随机数生成器,实现数据传输过程中的“一次一密”,并且采用了混合加密的算法,在同时保障了运行效率提高了安全性。To address the issues of unsecured IoT designs and traditional devices lacking communication capabilities failing to ensure secure data transmission,a hardware-software collaborative encryption scheme was adopted and deployed within the data transmission unit.This design is founded on national cryptographic algorithms and the LKT4305 encry-ption chip,featuring a built-in EC600N-CN communication module and hardware-software collaborative encryption mechanism to safeguard user data.Upon data retrieval,a pseudo-random number generator is invoked to implement"unique encryption for each session"during transmission,and a hybrid encryption algorithm is employed to enhance both operati-onal efficiency and security.
