摘　　要：在车辆装备远程故障诊断系统信息传输过程中，数据加密是保证信息安全的有效途径。鉴于此，提出了一种基于汉字编码字符集作密钥的方法——基于汉字密钥的私钥加密算法，在该系统信息传输中得到了很好应用。该算法加解密速度快、可靠性高，可应用于文字、语音、图像等多媒体数据的加密，可进行多媒体数据的实时加密。In the course of the long - distance vehicle fault diagnosis system＇ s information transmission, the data encryption is an effective way of ensuring the information security. The paper presents a key way based on the code collection of chinese characters, a private - key encrypting algorithm based on the chinese characters key. It is applied very well in the di- agnosis system＇ s information transmitting. We can encrypt the information rapidly by the algorithm. It has a strong reliabil- ity and can be applied to the multimedia information, such as the characters, phoneme, or images etc. It can encrypt the real- time multimedia data.
