| 摘 要： | 差分跳频是一种新型的跳频通信技术。基于仿射密码的加密原理，构造了一种差分跳频的频转移函数。该函数具有构造简单，便于密钥管理和控制，而且具有密钥量大的特点。最后通过实例说明了由该函数产生的跳频图案具有良好的均匀性，从而系统具有较强的隐蔽性和抗破译性。

| Abstract: | Differential frequency hopping (DFH) is a kind of new frequency hopping (FH) technique. Based on the encryption principle of affine cipher, a frequency transition function of DFH is designed. This function is convenient for realization, easy in controlling the secret keys and also has more secret keys. The final results of experiment prove that the frequency hopping pattern based on this function is good in uniformity, so the system has high complexity and strong anti-attack features. |
