摘要

差分跳频技术克服了传统跳频抗跟踪干扰能力较弱的问题。G函数算法决定了差分跳频序列的性能，也直接影响差分跳频系统的性能。然而随着无线系统的复杂化，如大容量的差分跳频系统，传统序列的应用受到严重挑战。因此，为了提升系统的安全性，提出了一种基于混合加密算法的 G 函数构造，证明了加密算法和 G 函数的等价性并分析了混合算法的安全性。仿真结果表明，新的G函数生成的序列性能优异，可以大幅度提升系统性能。

Abstract

The differential frequency hopping (DFH) overcomes the limitation of frequency hopping and improves the ability to resist tracking interference.The G function determines the DFH sequence and directly affects the performance of DFH communication systems.However

with the complication of wireless communication system such as large capacity DFH network

which poses huge challenges to the use of the number theory based and chaos theory assisted sequence.As a result

in order to improve the security of the system

the novel G function construction was proposed with the aid of hybrid encryption algorithm and the security of hybrid algorithm was analyzed.Moreover

the equivalence principle of G function algorithm and the encryption algorithm was proved.The simulation results show that the DFH sequence generated by the new G function has excellent performance and the performance of the DFH systems is improved greatly.
