| 摘 要： | 提出了对遥测PCM数据进行分组加密的方法,即建立了对遥测PCM数据进行"一次一密"的序列加密模型,并着重分析了加、解密系统及收发两端密钥同步的实现措施。仿真实验结果表明,所产生的密钥流序列基本满足伪随机序列的统计特性,加密变换后系统的误码率几乎没有变化。

| Abstract: | A packet encryption scheme of telemetry PCM data was proposed,which had established a model of sequence encryption also called the one-time pad(bit by bit) cipher,and analyzed the issue of encryption and decryption system,such as the synchronization measure between the sending and receiving ends in the PCM/FM telemetry system.The simulation results showed that the key stream sequence basically satisfied statistical properties of pseudo-random sequence,and the error rate of encrypted system was almost unchan... |
