摘要
针对两枚导弹同时攻击邻近目标时相互之间的指令干扰问题,提出了一种含有载机认证的无线电控制指令加密方案。方案结合对称密码学与非对称密码学的特点,利用非线性滤波函数产生密钥流对指令明文进行加密,并利用简化的数字签名实现了对制导指令的认证。描述了非线性滤波函数的构造、指令加密认证方案和算法的DSP实现与仿真,仿真结果表明该方案能很好地解决指令干扰问题,为综合更全面的航空电子系统的研究提供了有益的帮助。
Considering that the command of two missiles may interfere with each other when they attacking the nearby target at the same time,we put forward an encryption program for wireless command of TV-Guided missiles.The program combined the features of symmetrical cryptography with that of asymmetric cryptography,encrypted the command using the key stream produced by non-linear filter function,and realized command authentication using simplified digital signatures.The structure of the non-linear filter function,the encryption program and the DSP simulation of the program were described in the paper.Simulation results showed that the program provides a good solution to the interference problem,which provides a useful method for further study on integrated avionic system.
