中文摘要：

提出一种新的数据通信混合加密算法，结合AES、RSA、MD5的优点，解决了数据传输中的保密性、可鉴别性、和完整性的问题，并实现了在非安全信道下的密钥分配。将数据加密算法应用于远程智能终端RTU2600上，使用Dynamic C语言编译实现，提高了数据在工业网络中传输的安全性。

英文摘要：

A data hybrid encryption algorithm of data communication is proposed, This algorithm integrating the advantages of AES, RSA, MD5 could resolve the confidentiality, authentication, integrity in data communication and make possible key exchange in unsafe channel. This encryption algorithm of data can be used in the remote intelligent terminal RTU2600 to improve the safety of data transmission in industrial network with compiling under Dynamic C.
