摘　　要：阐述专用设备运行参数通信加密监控系统的设计。采用双层加密方式,分别设计适用于数据采集层的TEA-CTR对称加密算法和数据集成传输层的AES对称加密算法,以提高数据传输中的安全性和保密性。同时,在原有三层结构上增加密钥管理层,对整个系统数据传输的密钥实现动态管理,防止加密传输被轻易破坏。经实验验证,该设计可以在保证监控系统通信效率的前提下,满足安全传输要求,并且定期实现包括密钥分配、更新等功能,满足了对密钥保护的要求。This paper expounds the design of a specialized equipment operation parameter communication encryption monitoring system.The data encryption transmission adopts doublelayer encryption mode:the TEA-CTR symmetric encryption algorithm for data acquisition layer and AES symmetric encryption algorithm for data integration and transmission layer,to ensure the data transmission real-time performance and security.At the same time,in order to further improve the reliability of encrypted transmission,the key management layer is added to the original three-layer structure to realize the dynamic management of the key of the whole system data transmission and prevent the encryption transmission from being destroyed easily.The experimental results show that the design can meet the requirements of secure transmission on the premise of ensuring the communication efficiency of monitoring system,and periodically implement key distribution,update and other functions to meet the requirements of key protection.
