| 摘 要： | 分析了远程控制系统安全性设计要解决的两个方面问题：为防止未授权用户恶意破坏控制系统，提出了对付网络入侵者恶意操作控制系统的安全措施；为保证实时数据传输的快速性和安全性，将高级数据加密标准AES与网络通信加密协议SSL相结合，实现了适合于实时控制系统的数据加密算法，并通过测量实时数据加密传输的网络时延来验证该算法的有效性．

| Abstract: | Two essential safety design issues arising from features of internet based process control were studied. Safety measure for stopping malicious attacks from the outside and the encryption algorithm for real time data.In order to ensure real time and security for real time control systems, a data encryption algorithm was proposed. It was the combination of AES and secure sockets layer (SSL). The end to end encryption latency for real time data was tested and compared to show the efficacy of the new encryption algorithm for real time control systems based on Internet. |
