| 摘 要： | 我国新一代气象卫星探测资料种类繁多,资料发送方式多种多样,为了保证某种探测资料在特定环境下的授权使用,在数据传输过程中采用了加密和解密技术。在星上,对将要传输的数据通过分配的加密密钥进行加密处理;在地面,只对授权用户分配解密密钥,保证授权用户可以对接收到的数据进行解密处理,把数据恢复为可用状态。本文介绍了应用在新一代气象卫星数据传输过程中的加解密算法,并讲述了应用软件实现地面解密的过程。

| Abstract: | China's new generation meteorological satellites provide a variety of measurements,and various data need to be transmitted with different data transmission modes.To ensure that a certain kind of detection data can be appropriately used in specific conditions by only those who are authorized,encryption and decryption technology is applied in data transmission.Before transmission, data are encrypted with the encryption key on satellites;on the ground,the decryption keys are assigned to authorized users.The encryption and decryption algorithm of data processing for our new generation meteorological satellites is introduced,and the decryption process realized by software is described. |
